The Hike: What to Expect
The Rainbow Mountain hike is challenging primarily due to altitude. The trail itself is not technically difficult, but thin air makes it feel much harder.
Trail Overview
- Trailhead (15,420 ft / 4,700 m): Start point after 3-hour drive from Cusco
- First Section (1 hour): Gradual uphill on wide path, relatively easy
- Middle Section (45 min): Steeper climb, altitude becomes noticeable
- Final Push (30 min): Steep switchbacks to summit viewpoint
- Summit (17,060 ft / 5,200 m): Rainbow Mountain viewpoint, 20-30 min to enjoy
- Return (1.5-2 hours): Downhill back to trailhead
Difficulty & Altitude
Why it's challenging:
- Altitude: 17,060 ft is very high - 40% less oxygen than sea level
- Even fit people struggle due to thin air
- Steep sections near summit require frequent breaks
- Cold temperatures (often below freezing)
- Weather can change quickly (sun, rain, snow possible)
Important: Proper acclimatization is essential. Spend 2-3 days in Cusco before attempting.
Horse Option
Horses are available to rent ($20-$30 USD) for most of the trail. They can take you about 80% of the way - you still need to walk the final steep section.
- Good option if you're struggling with altitude
- Negotiate price before starting (usually $20-$30 USD)
- Horse handlers will walk alongside you
- You still need to hike the final 15-20 minutes

- Stay hydrated: Drink 3-4 liters of water per day
- Avoid alcohol: No drinking 24 hours before hike
- Eat light: Avoid heavy meals before and during hike
- Go slow: Walk at a steady, slow pace - no rushing
- Coca tea: Drink coca tea in Cusco and morning of hike
- Medication: Consider Diamox (consult doctor first)
- Listen to your body: Turn back if symptoms are severe
Warning: Do not attempt Rainbow Mountain on your first day in Cusco. Altitude sickness can be dangerous.
Rainbow Mountain vs Red Valley
Many tours now include Red Valley (Valle Rojo), an alternative viewpoint with fewer crowds and equally stunning colors.
Rainbow Mountain (Vinicunca)
- View: Classic rainbow stripes
- Crowds: Very busy
- Altitude: 17,060 ft (5,200 m)
- Best for: Iconic photo
Red Valley (Valle Rojo)
