Rainbow Mountain 3-day itinerary

Spend your first full day acclimatising in Cusco (3,400m). Walk slowly through the cobblestone streets of the historic centre — the Plaza de Armas with its colonial cathedral, the Inca stone walls on Hatunrumiyoc street (find the famous 12-angled stone), and the bohemian San Blas neighbourhood with artisan workshops and cafes. The key is to move gently — altitude sickness hits hard if you rush. Drink coca tea constantly, stay hydrated, and eat light meals. The San Pedro Market is a sensory overload of fresh juices, soups, and Andean ingredients.

Walk uphill (slowly) to Sacsayhuaman, the massive Inca fortress overlooking Cusco. The zigzag walls built from boulders weighing up to 200 tonnes fit together without mortar — the engineering is mind-boggling. The site offers panoramic views over the red-roofed city and surrounding mountains. Continue to the Cristo Blanco statue for sunset views. The walk back downhill through narrow streets leads past local picanterias (traditional restaurants) serving cuy (guinea pig) and chicharron — adventurous eating for the brave.

Cusco has a surprisingly vibrant backpacker scene. Grab dinner at a local restaurant — lomo saltado (stir-fried beef) or alpaca steak are Peruvian staples, both around 20–30 soles ($6–8). The bars around Plaza de Armas serve pisco sours for 10–15 soles ($3–4). But do not overdo it — alcohol amplifies altitude effects dramatically. Get an early night because the Rainbow Mountain pickup is between 3:30–4:30am tomorrow. Set multiple alarms.

Pickup from your hostel between 3:30–4:30am for the three-hour drive south through the Andean highlands. Watch the sunrise paint the mountains gold as you climb past 4,000m. Breakfast at a settlement near the trailhead includes bread, coca tea, and scrambled eggs. The trailhead at Quesiyuno sits at 4,600m — already higher than any mountain in Europe. Layer up with thermals, fleece, and a windbreaker. The morning air is biting cold but you will warm up quickly once walking.

The hike follows a gentle valley before a steep final push to 5,200m. Take each step deliberately — rushing at this altitude causes nausea, headaches, and worse. At the summit, the rainbow-striped mountainside spreads before you in bands of red iron, yellow sulfur, turquoise copper, and lavender clay. It looks unreal. Spend 20–30 minutes at the top for photos, then descend via the Red Valley — a hidden detour where entire hillsides glow deep crimson. Most hikers miss this because guides do not always mention it — insist on taking this route down.

Arrive back in Cusco by 5–6pm exhausted but euphoric. Your legs will feel like lead and the altitude will have drained you. Head straight to a hot shower, then treat yourself to a proper meal — Cusco has excellent restaurants at backpacker prices. A massage at one of the spas near the plaza ($15–20/hour) works wonders on tired muscles. The city looks magical at night with the cathedral lit up and the streets buzzing with travelers sharing stories of their mountain conquests.

Take a colectivo (shared van, 5 soles) to Pisac in the Sacred Valley. The Inca ruins perched on the mountainside above the town are spectacular and far less crowded than Machu Picchu. Terraced agricultural platforms cascade down the hillside with views across the entire valley. Below, the Pisac Market (especially busy on Tuesdays, Thursdays, and Sundays) sells handwoven textiles, ceramics, and alpaca wool clothing at prices far below Cusco. Bargain gently — start at half the asking price.

Continue by colectivo to Ollantaytambo (30 minutes from Pisac). This living Inca town still uses the original stone water channels and street layout from 600 years ago. The fortress-temple complex towers above the town — climb the steep terraces to the unfinished Sun Temple at the top for breathtaking views of the valley and the massive stone quarry across the river. The town itself is charming with narrow streets, traditional restaurants, and a relaxed vibe away from Cusco's tourist intensity.

Take a colectivo back to Cusco (2 hours, 10 soles) arriving by evening. Alternatively, spend the night in Ollantaytambo if you are heading to Machu Picchu the next day — hostels here cost $8–15 and the town is peaceful at night. Back in Cusco, celebrate your three days of Andean adventure with a farewell dinner. The Mercado San Pedro closes by 6pm but the restaurants around the plaza serve until late. Reflect on the fact that you hiked to 5,200m and survived — not everyone can say that.
