Koh Lanta 3-day itinerary

Ease into Koh Lanta at Long Beach, the island's main stretch of sand. Unlike the party beaches of southern Thailand, Long Beach is calm, wide, and unhurried. Swim in the bath-warm Andaman water, walk the full 3km length, or rent a stand-up paddleboard (400 THB/hour) from one of the beachside operators. Grab breakfast at a beachfront cafe — banana pancakes and Thai iced coffee for under 150 THB.

Ride south to Lanta Old Town on the island's quieter east coast. This atmospheric fishing village dates back over 100 years — stilted wooden shophouses line the waterfront, built by Chinese, Malay, and sea gypsy (Chao Ley) communities who traded across the Andaman. Visit the small Lanta Community Museum to learn about the island's multicultural history, browse local art galleries, and eat fresh crab curry at one of the waterfront restaurants overlooking the mangrove channel to Koh Lanta Noi.

Klong Dao Beach at the island's northern end is family-friendly and wide, with a gentle slope into shallow water. The sunset from here — framed by longtail boats and distant Ko Phi Phi silhouettes — is quintessential Andaman. Eat at one of the beachfront seafood restaurants where the day's catch is displayed on ice: choose your fish, pick your sauce (garlic, sweet chilli, or green curry), and pay by weight. A whole grilled barramundi with sides runs 250–400 THB.

Join a Four Islands snorkelling tour (800–1,200 THB from any tour shop on Long Beach) departing at 8am. The traditional longtail boat heads first to Koh Chuek, a tiny limestone island with a shallow coral reef teeming with parrotfish, triggerfish, and Nemo clownfish in their anemone hosts. The second stop is Koh Mook and its famous Emerald Cave (Tham Morakot) — you swim 80 metres through a pitch-dark sea cave tunnel to emerge in a hidden lagoon surrounded by towering jungle-covered cliffs, open to the sky. The lagoon has a tiny white beach.

The boat continues to Koh Ngai (also called Koh Hai), a small island with a stunning white sand beach and coral reef starting just metres from shore. Snorkel directly off the beach among schools of butterflyfish and blue-spotted stingrays in crystal-clear water. Lunch is included on most tours — typically pad thai, fried rice, and fresh fruit served on the beach. The final stop is Koh Maa (sometimes called Paradise Beach), a sandbar island connected to Koh Lanta's northwest tip, with calm shallow water perfect for a final swim.

Back on Koh Lanta, head to Kantiang Bay on the southern half of the island — a crescent-shaped bay that many consider the island's most beautiful beach. The bay is quieter and more upscale than the northern beaches. Eat at Same Same But Different, a beachfront restaurant with excellent massaman curry and fresh prawns grilled with garlic (250 THB). The bay faces directly west, and the sunset here — framed by jungle-covered headlands on both sides — is intimate and spectacular.

Ride to the southern tip of Koh Lanta to Mu Ko Lanta National Park (200 THB entry). The lighthouse at Tanod Cape stands on dramatic rocks overlooking the open Andaman Sea — on clear days you can see Ko Rok and Ko Haa on the horizon. Walk the nature trail through coastal forest filled with monitor lizards, hornbills, and macaques. The park's secluded beaches are pristine and rarely crowded — swim off the rocks where the snorkelling reveals colourful coral and reef fish just below the surface.

Head to Thung Yee Pheng on the east coast for a kayaking tour through Koh Lanta's mangrove forests (500–700 THB for 2 hours). Paddle through tunnels of twisted mangrove roots, spotting mudskippers, fiddler crabs, kingfishers, and occasionally monitor lizards sliding silently into the water. The mangrove ecosystem is a vital nursery for fish and shrimp that sustain the island's fishing communities. Several operators offer guided tours with ecological commentary.

Spend your last afternoon on Klong Nin Beach — a quieter mid-island beach popular with long-stay travellers, with a more local feel than the northern stretches. Watch one final Andaman sunset from a hammock strung between coconut palms. For your onward journey, minivans to Krabi town depart until 4pm (350 THB, 2 hours), connecting to ferries to Koh Phi Phi, or direct boats to Koh Lipe in the deep south during high season (November–April).
