Koh Rong
Cambodia's wild island paradise — pristine white sand beaches, bioluminescent plankton, and untouched jungle on one of Southeast Asia's last undeveloped islands.
1 day in Koh Rong
Only got 24 hours? Here's how to experience the best of Koh Rong in a single action-packed day.
Koh Rong Highlights
Long Set Beach & Swimming
Arrive on the morning ferry from Sihanoukville and head straight to Long Set Beach (also known as Long Beach or 4K Beach) — a staggering 7-kilometre stretch of pristine white sand on the island's west coast that ranks among the most beautiful beaches in Southeast Asia. The sand is powder-fine, the water is warm and crystal clear, and the beach is backed by untouched tropical jungle. In the morning the beach is virtually empty — you may walk for half an hour without seeing another person. Swim in the calm turquoise water and dry off on the sand while watching hornbills fly between the trees.
Jungle Trek to Sok San Village
Follow the cross-island trail from Long Set Beach through dense tropical jungle to Sok San village on the east coast — a traditional Khmer fishing community of about 500 people that has existed long before any tourists arrived. The trail takes about 40 minutes and passes through thick forest where you may spot macaques, monitor lizards, and colourful tropical birds. Sok San itself is a ramshackle but charming village with wooden stilt houses, fishing boats, and a small school. Grab a cold drink from the village shop and chat with the friendly locals before heading back.
Bioluminescent Plankton Night Swim
Koh Rong is one of the best places in the world to see bioluminescent plankton — microscopic organisms that glow electric blue when disturbed in the water. On moonless nights, the phenomenon is spectacular: every movement in the water creates trails of blue light, as if swimming through liquid stars. The best spots are along Long Set Beach and around the pier at Koh Toch village. Wade into the dark water and sweep your hands to trigger the glow — it is genuinely one of the most magical natural experiences you will ever have.
3 days in Koh Rong
A carefully curated route mixing iconic landmarks, hidden gems, street food, culture, and adventure — designed for younger travelers.
Long Set Beach & Bioluminescence
Ferry to Koh Rong & Long Set Beach
Take the morning speed ferry from Sihanoukville to Koh Rong — the journey takes 45 minutes across the Gulf of Thailand. Ferries arrive at Koh Toch village, the island's small tourist hub with guesthouses, restaurants, and dive shops. From the pier, take a boat taxi or walk the jungle trail to Long Set Beach on the west coast. This 7-kilometre sweep of white sand is one of Cambodia's finest beaches — utterly unspoiled, backed by thick jungle, and with water so clear you can see fish swimming from the shore. Drop your bag at a beach bungalow and spend the morning swimming and exploring.
Snorkelling at Long Set Reef
The southern end of Long Set Beach has a rocky reef that offers the best shore-accessible snorkelling on the island. Rent a mask and fins from your bungalow or beach bar (about $5 per day) and swim out to the rocks where you will find hard and soft coral, lionfish, pufferfish, and schools of damselfish and wrasse. The visibility is excellent during the dry season — 10 to 15 metres is common. Further along the coast, the reef becomes deeper with larger formations and more diverse marine life. If you are a confident swimmer, the rocks at the far southern headland have the healthiest coral.
Bioluminescent Plankton Night Swim
After dinner at one of the simple beach restaurants, wait for full darkness and head to the waterline for Koh Rong's most magical experience — bioluminescent plankton. On dark nights, the water glows electric blue with every disturbance. Wade in and sweep your arms through the water to create swirling trails of blue light, or swim further out where each stroke leaves a glowing wake behind you. It is caused by dinoflagellates — single-celled organisms that emit light as a defence mechanism. The effect is strongest between October and May on moonless nights.
Diving, Jungle Trek & Sok San
Scuba Diving or Snorkel Trip
Join a morning dive or snorkel trip with one of the island's dive operators — Dive Shop Koh Rong and The Dive Shop are both reputable outfits based at Koh Toch. The island has several excellent dive sites including Japanese Garden (a coral-covered slope with seahorses and nudibranchs), Six Senses (named after the luxury resort nearby), and the deeper offshore reefs where barracuda, rays, and occasional whale sharks have been spotted. A two-dive trip costs about $65-80 for certified divers. Discover scuba dives for beginners are available for around $80.
Jungle Trek to Sok San Village
After returning from the dive, hike the cross-island jungle trail from the main pier area to Sok San village on the east coast. The trail winds through dense tropical forest alive with the sounds of cicadas, birds, and rustling undergrowth — macaques are commonly seen swinging through the canopy. Sok San is a traditional Khmer fishing village where life has changed little in generations: wooden stilt houses, nets drying on the shore, and children playing in the shallows. Visit the village temple and school, buy a cold drink from the tiny shop, and sit on the dock watching the fishing boats return.
Koh Toch Village Nightlife
Return to Koh Toch village — the island's small but lively tourist hub where backpackers, divers, and expats gather at the waterfront bars. The nightlife is unpretentious and social: cheap beers ($1-2), hammocks on the sand, fire shows, and music that ranges from reggae to techno depending on the bar. The Nest Beach Club and Skybar at Police Beach are the main party spots, while smaller beach bars offer a more chilled atmosphere. Grab dinner at one of the Khmer restaurants — amok (coconut fish curry), lok lak (stir-fried beef), and fried rice are all excellent and cost $3-5.
Police Beach, Kayaking & Departure
Police Beach & Hidden Coves
Walk or take a short boat taxi to Police Beach — a small, photogenic bay south of Koh Toch named after a police outpost that once stood here. The beach is sheltered by jungle-covered headlands and has some of the clearest water on the island — excellent for snorkelling directly from the shore. From Police Beach, follow the rocky coastal path south to discover a series of tiny hidden coves that are completely empty on most days. Each pocket beach is more beautiful than the last, with white sand, overhanging tropical trees, and water that shimmers between turquoise and emerald.
Kayaking the West Coast
Rent a kayak from one of the beach bungalow operations and paddle along the west coast of Koh Rong. The coastline is spectacular from the water — towering jungle, rocky headlands, and small sandy coves only accessible by boat. Paddle north from Long Set Beach and you will find completely deserted stretches of sand where you can pull up and have a private beach entirely to yourself. The water is calm in the dry season and the kayaking is easy. Keep your eyes open for sea eagles soaring above the treeline and occasionally dolphins playing offshore in the deeper water.
Sunset & Ferry Departure
Spend your final hours on Koh Rong at your favourite beach spot, watching the sun set over the Gulf of Thailand. The west coast beaches face directly into the sunset and the sky turns spectacular shades of orange and purple as the sun drops below the horizon. Grab a final amok curry and cold Angkor beer at a beachside restaurant before catching the evening ferry back to Sihanoukville. Koh Rong is one of those rare places that still feels genuinely undiscovered — savour the peace and simplicity before returning to the mainland.
7 days in Koh Rong
A full week to go deep — from famous landmarks to local neighbourhoods, day trips, hidden gems, and proper local immersion.
Arrival & Long Set Beach
Ferry to Koh Rong
Take the morning speed ferry from Sihanoukville's Serendipity pier to Koh Rong — a 45-minute crossing over the Gulf of Thailand. The ferry docks at Koh Toch village, the island's main (and still very small) tourist hub. Drop your bags at your chosen guesthouse and orient yourself — Koh Toch has a small beach, a cluster of restaurants and bars, dive shops, and the island's only ATM. Pick up any supplies you need before heading out to explore, as facilities outside of Koh Toch are extremely basic.
Long Set Beach — First Swim
Take a boat taxi ($5) or walk the jungle trail (45 minutes) to Long Set Beach on the west coast. This 7-kilometre stretch of pristine white sand is the main reason most people come to Koh Rong — it is genuinely one of the most beautiful beaches in Southeast Asia. The sand is fine as flour, the water is bathtub-warm and crystal clear, and the jungle behind is thick and untouched. Find a bungalow or hammock spot, swim, read, and decompress from mainland life. The pace on Koh Rong is wonderfully slow and there is no pressure to do anything but exist.
Beach BBQ & Stars
The beach bungalow restaurants along Long Set serve simple but satisfying meals — grilled fish, fried rice, vegetable curry, and banana pancakes are the staples. Many places set up beach BBQs in the evening where freshly caught fish and squid are grilled over coconut husks on the sand. The island has very little light pollution and the night sky from Long Set Beach is extraordinary — the Milky Way stretches from horizon to horizon and shooting stars are common. Lie on the sand and stargaze while listening to the gentle waves — this is island life at its most elemental.
Snorkelling & Bioluminescence
Snorkelling the Southern Reef
Head to the southern end of Long Set Beach where a rocky reef extends into deeper water. This is the best shore-accessible snorkelling on Koh Rong with healthy hard and soft coral, lionfish, pufferfish, moray eels, and dense schools of damselfish and butterflyfish. The visibility during the dry season regularly exceeds 10 metres and the water is calm and warm. Spend the morning alternating between the reef and the beach — the snorkelling is easy and suitable for all levels. For the best marine life, swim beyond the shallow rocks to the deeper coral formations.
Beach Exploration & Hammock Time
Spend the afternoon exploring Long Set Beach at your own pace. Walk north along the sand to the less-visited stretches where you can have entire sections of beach to yourself. The jungle treeline is full of coconut palms, sea almond trees, and the occasional hermit crab making its way across the sand. Find a hammock at one of the scattered beach bars, order a fruit shake, and settle into the rhythm of the island. Read a book, journal, or simply watch the waves — Koh Rong rewards those who slow down completely.
Bioluminescent Plankton
After dinner, head to the water's edge for the island's most unforgettable experience — bioluminescent plankton. When darkness is complete (best on moonless nights), walk into the shallows and every step creates an explosion of electric blue light. Swimming creates glowing trails that follow your body through the water. Splash the surface and watch the blue sparks scatter like underwater fireworks. The phenomenon is caused by dinoflagellates — single-celled organisms that produce light when mechanically disturbed. It is completely natural, completely harmless, and completely mind-blowing.
Diving Day
Two-Tank Dive Trip
Join a morning two-tank dive trip with a local operator. The dive sites around Koh Rong include Japanese Garden — a gently sloping coral reef with seahorses, nudibranchs, and vibrant soft corals — and deeper offshore reefs where larger marine life patrols. The water temperature is a comfortable 28-30°C year-round so a thin wetsuit or rash guard is sufficient. A two-dive trip for certified divers costs $65-80 including gear. If you have never dived before, discover scuba experiences start at about $80 and include pool training before an open water dive.
Koh Toch Village & Recovery
After diving, spend the afternoon at Koh Toch village recovering with food and rest. The small cluster of restaurants serves both Khmer and international food — try the fish amok (Cambodia's national dish, a coconut curry steamed in banana leaf) or a simple fried rice with egg. Browse the handful of shops selling island essentials, hammock-weave bracelets, and basic snorkel gear. If you have energy, walk to the small headland south of Koh Toch for elevated views back over the village and out to Koh Rong Samloem, the quieter neighbouring island visible across the channel.
Koh Toch Bar Scene
Koh Toch's small but lively bar scene is the social hub of Koh Rong. The waterfront bars serve cheap Angkor beer ($1-2), cocktails, and buckets while fire dancers perform on the beach after dark. The crowd is an international mix of backpackers, dive instructors, and expats — conversation flows easily and the atmosphere is friendly and unpretentious. The Nest Beach Club plays electronic music and attracts a younger crowd, while the quieter bars further from the pier offer hammocks and reggae for a more relaxed vibe.
Sok San & East Coast
Jungle Trek to Sok San Village
Hike the cross-island jungle trail from the main pier area to Sok San village on the east coast. The 40-60 minute trail passes through dense tropical forest alive with the sounds of insects, birds, and cracking branches from macaques in the canopy. The vegetation is thick — massive dipterocarp trees, wild banana plants, and tangled vines. Sok San is a traditional Khmer fishing village of about 500 people where wooden stilt houses line the waterfront and fishing nets dry on the shore. Visit the village temple, watch the fish being sorted at the dock, and see a side of Cambodia that has nothing to do with tourism.
Sok San Beach & Swimming
Sok San Beach on the east coast is a quieter alternative to Long Set Beach with a different character — the sand is slightly coarser, the water is shallower, and the view looks east over the channel to the mainland coast. A handful of basic bungalow operations have set up here, catering to travellers who want even more seclusion than the west coast offers. Swim, sunbathe, and enjoy the solitude — on a weekday you may be the only visitor on the entire beach. The local fishermen sometimes sell fresh seafood at the waterfront which the bungalow restaurants will cook for you.
Sunset from the Hilltop
Return to the west coast via the jungle trail in time for sunset. Climb the small hill behind Koh Toch village for an elevated view over the bay and offshore islands as the sun drops into the Gulf of Thailand. The sky turns dramatic shades of orange and pink reflected in the calm water below. Head down for dinner at one of the Khmer restaurants — the seafood fried rice and tom yum soup are consistently good and cost $3-5. End the evening in a hammock on the beach with a cold drink, listening to the waves.
Koh Rong Samloem Day Trip
Boat to Koh Rong Samloem
Take a morning boat taxi or local ferry to Koh Rong Samloem — Koh Rong's smaller, quieter sister island, 20 minutes south across the channel. Saracen Bay on the east coast is the main beach — a perfect horseshoe of white sand fringed by coconut palms with calm, shallow water ideal for swimming. The island has fewer facilities and visitors than Koh Rong, making it feel even more remote and unspoiled. The water clarity here is exceptional — you can see the sandy bottom in 5 metres of water from the beach.
Lazy Beach & Snorkelling
Walk or boat around to Lazy Beach on the south coast of Koh Rong Samloem — a secluded bay with just one small resort and some of the best snorkelling accessible from shore in the entire archipelago. The reef here is healthy and diverse with hard table corals, brain corals, and an impressive variety of tropical fish. Bamboo sharks rest on the sandy bottom in the shallows and clownfish nestle in their anemone homes along the reef edge. The beach itself is tiny and intimate — white sand, clear water, and jungle on all sides.
Return & Quiet Night on Koh Rong
Take the boat back to Koh Rong in the late afternoon and spend a quiet evening on Long Set Beach. The contrast between the two islands is interesting — Koh Rong Samloem is even more raw and undeveloped, while Koh Rong has just enough infrastructure to be comfortable without losing its wild character. Grab dinner at your favourite beach spot and watch the stars come out. If conditions are right, walk to the water for another session with the bioluminescent plankton — it never gets old, no matter how many times you see it.
Hidden Beaches & Kayaking
Police Beach & Secret Coves
Walk south from Koh Toch to Police Beach — a pretty sheltered bay with clear snorkelling water and a handful of beach bars. From the southern end of Police Beach, scramble along the rocky coastline to find a series of tiny hidden coves that most visitors never discover. These pocket-sized beaches are completely private on most days — perfect for swimming, snorkelling, and feeling like a castaway. The rock formations between the coves are fascinating, shaped by millennia of waves into arches, overhangs, and tide pools teeming with crabs and small fish.
Kayaking the West Coast
Rent a sea kayak from one of the beach operations and paddle along the west coast of Koh Rong. The coastline from the water is stunning — unbroken jungle rising from white sand beaches, rocky headlands with crashing waves, and small coves accessible only by boat. Paddle south from Long Set Beach and you will find deserted stretches of sand where you can pull up the kayak and swim without another person in sight. The water is usually calm in the dry season and the paddling is easy and meditative. Look out for sea eagles hunting above the treeline and fish jumping in the shallows.
Sunset & Seafood BBQ
Return the kayak and find a spot on Long Set Beach for the sunset — the west coast faces directly into the setting sun and the display is consistently spectacular. Several beach bungalow restaurants set up evening BBQs where fresh fish, squid, and prawns are grilled over coals on the sand. Sit on a beach cushion with a plate of grilled seafood, a cold beer, and the afterglow of the sunset painting the sky in fading pastels. Koh Rong's simplicity is its greatest charm — no fancy restaurants, no nightclubs, just sand, sea, and honest food.
Final Day & Departure
Sunrise Swim & Beach Walk
Wake early for a final sunrise swim on Long Set Beach. The east-facing sunrise illuminates the jungle canopy behind the beach in golden light while the water takes on a glassy, mirror-like quality in the still morning air. Walk the full length of the beach one last time — 7 kilometres of uninterrupted white sand that in a few years may look very different as development creeps in. For now, Koh Rong remains one of Southeast Asia's last truly wild island beaches. Take your time and commit the feeling to memory.
Final Snorkel & Pack Up
Spend your final morning snorkelling the reef one last time or simply lying on the beach soaking up the last of the island atmosphere. Pack up your belongings and walk or boat back to Koh Toch village for the ferry departure. Grab lunch at one of the village restaurants — a final fish amok and iced coffee make a fitting farewell meal. Browse the small souvenir stalls for handmade bracelets and coconut crafts. Say goodbye to the dive instructors, bar staff, and fellow travellers who have made your island week memorable.
Ferry to Sihanoukville & Onward
Catch the afternoon ferry back to Sihanoukville and reflect on a week spent on one of Southeast Asia's most beautiful and unspoiled islands. Koh Rong is changing rapidly — new resorts and an international airport are planned — so the raw, wild character you experienced may not last forever. From Sihanoukville you can bus to Phnom Penh (5 hours), Kampot (3 hours), or continue exploring the Cambodian coast. Alternatively, night buses run directly to Bangkok and Ho Chi Minh City for those continuing their Southeast Asia journey.
Budget tips
Stay at beach bungalows
Simple wooden bungalows on Long Set Beach start at $8-15 per night — basic but right on the sand. Koh Toch has slightly more upmarket options but you lose the beach-living experience.
Eat Khmer food, not Western
A plate of amok or fried rice costs $3-5 at local restaurants. Western food (burgers, pizza) is imported and costs twice as much. Eat local for better food at lower prices.
Bring cash from the mainland
Koh Rong has one ATM with unreliable power and high fees. Withdraw what you need in Sihanoukville before boarding the ferry to avoid getting stuck without cash.
Snorkel from shore, not boats
The reef at the southern end of Long Set Beach is accessible by swimming — no need for expensive boat trips. Buy a $10 snorkel set in Sihanoukville and use it daily.
Walk instead of boat taxi
The jungle trail between Koh Toch and Long Set Beach takes 45 minutes and is free. Boat taxis charge $5-10 per trip — walking saves $10-20 per day and is more adventurous.
Book ferry tickets in advance
Walk-up ferry prices can be inflated, especially during peak season. Book online or at the Sihanoukville pier the day before for the best rates.
Budget breakdown
Daily costs per person in US dollars. Koh Rong is one of Southeast Asia's cheapest island destinations — budget backpackers can live on $20-30 per day, while mid-range comfort runs $50-80.

Practical info
Entry & Visas
- Cambodia tourist visa: $30 on arrival or eVisa in advance — 30 days, extendable
- You need a passport photo for visa on arrival — bring one or pay $2 for a photo at the border
- Koh Rong is reached by ferry from Sihanoukville — no direct international access
Health & Safety
- The island has a small clinic but serious injuries require boat transfer to Sihanoukville — travel insurance with medical evacuation is essential
- Mosquitoes carry dengue and malaria — use repellent, sleep under a net, and wear long sleeves at dusk
- Sandflies are common on the beach — coconut oil or DEET-based repellent helps. Bites are intensely itchy and take days to heal
Getting Around
- Koh Rong has no roads or vehicles — getting around is by walking, jungle trails, or boat taxis
- Boat taxis between beaches cost $5-10 per person per trip — establish the price before boarding
- The main jungle trail between Koh Toch and Long Set Beach takes 45-60 minutes and is the primary overland route
Connectivity
- Mobile signal is available at Koh Toch and intermittent elsewhere — Cellcard and Smart have the best coverage
- WiFi exists at some guesthouses and bars but is slow and unreliable — do not count on it for work
- Download offline maps, books, and entertainment before arriving. Expect to disconnect — that's part of the appeal
Money
- USD is the primary currency — riel is used for small change (4,000 KHR = $1). Bring USD cash in small denominations
- The island has one ATM at Koh Toch with unreliable power — never depend on it. Bring enough cash from Sihanoukville
- Tipping is not expected but appreciated — $1 for good restaurant service is generous by local standards
Packing Tips
- Pack light — you will be walking jungle trails and getting in and out of boats. A small backpack is better than a large suitcase
- Essential items: reef shoes, headlamp, mosquito repellent, basic first aid kit, and a dry bag for boat transfers
- Power outages are common — bring a portable battery pack. Some bungalows have limited charging hours
Cultural tips
Koh Rong is a rare gem — approach it with respect for its fragile ecosystem and the Khmer communities who have lived here for generations, and you will experience island life at its most raw and beautiful.
Respect Khmer Culture
Cambodia is a Buddhist country with strong cultural traditions. When visiting Sok San village or any temple, dress modestly and behave respectfully. Remove shoes before entering homes or temples. Greeting with a sampeah (palms together, slight bow) is appreciated.
Protect the Island Environment
Koh Rong's ecosystem is fragile and increasingly threatened by development and tourism waste. Take all rubbish with you — the island has no proper waste management. Use reef-safe sunscreen, do not touch coral, and never feed marine life.
Photography & Privacy
Ask permission before photographing local villagers, especially at Sok San. Children may want to pose but it is polite to ask their parents first. Do not photograph military or police installations.
Language & Communication
Learn basic Khmer — suo sdei (hello), aw kun (thank you), and chnam (delicious) earn genuine smiles. Most tourist-facing Cambodians speak some English but the effort to use their language is deeply appreciated.
Support Local Livelihoods
Choose locally-owned bungalows and restaurants over foreign-owned establishments. Buy from Sok San village vendors. The fishing families of Koh Rong have lived here for generations — supporting their economy helps preserve the community.
Island Pace & Patience
Infrastructure on Koh Rong is basic and things do not always work. Generators fail, boats run late, and menus have limited availability. Embrace the imperfection — the trade-off is an island experience that has not yet been polished into a resort product.
