Two Days to the Colors: A Small-Group Trek to Peru’s Rainbow Mountain
A quieter, higher route to Vinicunca with glacier views, starlit camping, and fewer crowds
The wind carries a thin, clean chill as the trail rises past stone corrals and a scatter of grazing alpaca. Above you, Ausangate—the great snow-bellied Apu—watches, glistening with late light that cuts like a blade. The mountain seems to set the tempo: slow, steady, patient. Your group follows, eight trekkers max, quiet in the thin air. The trail steps calmly through tawny puna grass and past lakes so clear they mirror the sky. The Andes don’t shout here; they speak in steady breaths and long horizons.
Trail Wisdom
Acclimatize in Cusco
Spend 2–3 days in Cusco before the trek to let your body adjust to altitude and reduce the risk of headaches or fatigue.
Layer for Big Swings
Expect frosty mornings, strong midday sun, and a quick evening cooldown—pack and wear layers you can adjust on the move.
Start Early for Clear Views
Sunrise to midmorning offers calmer winds and fewer crowds at Vinicunca and Red Valley overlooks.
Hydrate Relentlessly
Drink small amounts often and add electrolytes; dehydration hits faster at 5,000 meters.

Conservation Note
Stay on established trails to protect fragile alpine soils and the colorful sediment layers around Vinicunca. Community-managed fees support local stewardship—carry cash and pack out all waste.
Ausangate is a sacred Apu to local Quechua communities, honored during the annual Qoyllur Rit’i pilgrimage near the mountain.
Seasonal Guide
spring
Best for: Shoulder-season solitude, Wildflower-dotted valleys
Challenges: Afternoon showers, Occasional hail and mud
September–November brings light crowds and fresh greens, with changeable weather that can shift from sun to squalls.
summer
Best for: Dramatic skies for photography, Quieter trails
Challenges: Heaviest rain and thunderstorms, Slippery terrain and limited visibility
December–February is the wet season; expect soft trails and frequent storms—rewarding if you’re prepared, risky if you’re not.
fall
Best for: Clearing weather, Stable trail conditions
Challenges: Lingering showers early in the season, Cold nights at camp
March–May transitions to dry; by May you’ll often see crisp mornings, steady afternoons, and big night skies.

Challenges: Freezing nights and biting wind, Intense UV exposure
June–August is peak dry season—stellar visibility, strong sun, and subfreezing nights in camp.
Photographer's Notes
What to Bring
Broken-in Waterproof Hiking BootsEssential
Rocky, sometimes muddy trails demand support and traction at high altitude.
Waterproof-Breathable Shell JacketEssential
Wind and sudden showers are common above 4,000 m; a reliable shell keeps you dry and warm.
Insulated Midlayer (Down or Synthetic)Essential
Nights drop below freezing even in dry season; insulation is your camp comfort.
Trekking Poles
Helpful for steep descents and long grades, especially when the trail is slick.
Common Questions
How difficult is the trek to Rainbow Mountain on this 2-day route?
It’s a challenging, non-technical hike primarily due to altitude. Expect several hours of hiking each day with sustained climbs above 4,500 m and a high point over 5,000 m.
Do I need to acclimatize in Cusco first?
Yes. Plan 2–3 days in Cusco (3,400 m) before the trek to help your body adapt and reduce the risk of altitude sickness.
What is the highest altitude reached?
The Rainbow Mountain viewpoint sits just over 5,000 m (around 16,400–16,600 ft), with camps typically around 4,300–4,600 m depending on the route.
Are there bathrooms on the trail?
Basic facilities exist at trailheads and camps. Between those points, follow Leave No Trace practices and carry out toilet paper.
Can dietary needs like vegetarian or gluten-free be accommodated?
Most outfitters can accommodate with advance notice. Confirm specifics at booking time.
Will my phone work out there?
Cell service is limited to nonexistent along most of the route; plan for offline maps and no connectivity until returning toward Cusco.
What to Pack
High-SPF sunscreen and lip balm for intense UV; 2–3L hydration system to keep sipping at altitude; warm hat and gloves for subfreezing nights; small bills in Peruvian soles for community entrance fees and tips.
Did You Know
Rainbow Mountain’s colors come from mineral-rich sediments: iron oxides create reds, goethite/limonite produces yellows, and chlorite lends green hues. The site became widely known only in the 2010s as snow cover retreated.
Quick Travel Tips
Book a small-group operator to avoid the main-day crowds; spend 2–3 nights in Cusco before hiking; download offline maps and keep devices in airplane mode; expect and carry cash for local community fees (no cards at the trailhead).
Local Flavor
Back in Cusco, refuel with a trout ceviche or alpaca steak at Pachapapa in San Blas, then sip a craft brew from Cervecería del Valle at Limbus Restobar with a citywide view. For a local reset, wander San Pedro Market—fresh juices, coca leaves, chuta bread—and pick up a warm llama wool beanie.
Logistics Snapshot
Fly into Alejandro Velasco Astete International Airport (CUZ) in Cusco. Drive time to the trailhead via Cusipata/Phulawasipata is about 3 hours each way. Cell service is scarce beyond the villages—expect radio/guide communication only. No formal permits are required, but community entrance fees are collected in cash at access points.
Sustainability Note
This high Andean ecosystem recovers slowly—stay on the main path, don’t climb on the colored slopes, and avoid disturbing wildlife and herds. Pack out all trash and use refillable bottles; most operators can provide treated water.
