Red Valley Peru (Valle Rojo): The Complete 2025 Guide

Hidden behind the famous Rainbow Mountain lies one of Peru’s most surreal landscapes: the Red Valley (Valle Rojo). This vast canyon with iron-rich slopes, deep red ridges, and glacier-formed amphitheaters is often described as the quieter, grander, and more dramatic sibling of Vinicunca.

While Rainbow Mountain attracts thousands of visitors every day, the Red Valley receives only a fraction of those visitors—making it a dream destination for hikers seeking solitude, larger panoramas, and a truly Martian-like landscape.

This complete travel guide tells you everything you need to know in 2025, including distance, altitude, safety, best time to visit, fees, how to get there, and why adding the Red Valley is one of the best additions to any Rainbow Mountain and Red Valley tour.

What is the Red Valley in Peru?

The Red Valley in Peru is a huge geological basin behind Rainbow Mountain in the Pitumarca district (Cusco region). Its unique coloration comes from iron oxide and other mineral-rich sediments exposed by millions of years of tectonic uplift and glacial erosion.

The result?
A natural landscape in:

• deep red tones
• burnt orange tones
• rust-brown layers
• contrasting patches of green chlorite
• snow-capped ridges in the distance

Hiking across the ridge into the valley is like walking through a natural amphitheater carved entirely in red.

Where is the Red Valley?

The Red Valley is located just 20 to 30 minutes behind the Rainbow Mountain viewpoint in the Andean highlands of southern Peru.

• Distance from Cusco: 3 hours by car
• District: Pitumarca
• Province: Canchis
• Region: Cusco

The valley starts at an altitude of about 5,000 m (16,400 ft), with the highest viewpoints reaching about 5,200 m (17,060 ft).

Due to the high altitude, it is strongly recommended to acclimatize in Cusco for 1–2 days before the hike.

Why is the Red Valley so red? (The geological background)

The intense coloration of the Red Valley is the result of:

• Iron oxide (hematite) → causes red and rusty hues
• Chlorite → causes green spots
• Sandstone and claystone layers → cause striped structures
• Glacial erosion → exposes fresh mineral surfaces

This is the same geological system that created Rainbow Mountain, but the Red Valley has a much higher concentration of iron oxides, which is why the color appears stronger and more uniform across the entire slopes, it really feels like walking on Mars.

How challenging is the hike to the Red Valley?

The extension to the Red Valley is considered moderately difficult, but due to the altitude, it appears more challenging.

Difficulty Level:

Moderate (due to the altitude, not the distance)

Distance and Time:

• 20–30 minutes one way from the summit area of Rainbow Mountain
• Total hiking time for Rainbow Mountain + Red Valley: 3–4 hours

Notes on the hiking trail: Short but steep sections near the viewpoint, the thin air above 5,000 m affects breathing and pace. The weather in the area can change quickly – sun, wind, snow, or clouds. Considere to be well acclimated to the altitudes in Cusco, as even for experienced hikers, the altitude is the real challenge.

Best time to visit the Red Valley (monthly insights)

The Red Valley is accessible year-round, but conditions vary significantly depending on the season.

Dry season (best time to visit): April–November

• Most intense red colors
• Clear skies, especially in the early morning
• Cold, often below freezing at dawn
• Very windy at midday
• Hiking trails are dry and easier to walk on

Intermediate months: March and December

• Mixed conditions
• Colors still vibrant
• Rain possible in the afternoon

Rainy season: January–February

• Trails may be muddy
• Snowfall possible, which can cover the colors
• Clouds may impair visibility
• Tours may be canceled due to weather

Note: If you are a photographer, the best time to go is May–September, right after sunrise.

Entrance fee for the Red Valley

To enter the Red Valley, travelers must pay a fee administered by the municipality, which is usually as follows:

• 30 S/ (Peruvian soles)
• Cash only
• The fee is paid at a small checkpoint at the beginning of the detour to the Red Valley.

This fee is separate from the entrance fee for Rainbow Mountain, as each area is managed by a different municipality.

How to Get to the Red Valley (two Reliable Options)

OPTION 1 – Add-on to the Rainbow Mountain tour (recommended)

The safest, easiest, and most common way to get to the Red Valley is to take a guided day tour to Rainbow Mountain that includes a detour to the Red Valley.

A typical itinerary looks like this:

1. Departure from Cusco: between 3:00 and 3:30 a.m.
2. Breakfast break: near Cusipata or Chillihuani
3. Drive to the starting point of the hike: 4,600–4,700 m
4. Start of the hike: 60–120 minutes to the Rainbow Mountain viewpoint
5. Detour to the Red Valley: follow the signposted path “Valle Rojo / Red Valley”
6. Pay community fee: cash only

Return via the same ridge OR descend via the hiking trail through the Red Valley (depending on the guide’s approval and the weather)

Why this option is better:

• Licensed guides
• Oxygen available
• First-aid support
• Breakfast + lunch included
• Safe private transport
• Early departures help beat crowds & weather

OPTION 2 – Independent visit (possible, but not recommended)

Travelers can combine an independent visit with:

• Public transportation from Cusco
• Local taxis from Pitumarca or Checacupe
• Transfers to the starting point of the hike

You will then hike to Rainbow Mountain and continue on to the Red Valley.

Advantages:

• Complete freedom in terms of pace and timing
• More time at the summit or in the valley

Disadvantages:

• Multiple transfers (may equal or exceed the cost of the tour)
• Minimal signage
• No medical care or oxygen
• You still have to pay both entrance fees for the communities.
• Weather changes can make the return route difficult.

For most visitors especially at altitudes above 5,000 meters a guided tour is significantly safer.

Weather in Red Valley (What to expect)

The weather at this altitude changes every 15 to 30 minutes.

You can expect:

• Very cold mornings (often below 0 °C / 32 °F)
• Strong UV radiation throughout the year
• Possible snowfall even during the dry season
• Sudden gusts of wind on the mountain ridge
• Clouds rolling in quickly in the afternoon

Always check the weather conditions early in the morning, as thicker clouds often form in the afternoon.

Altitude & Safety tips

At an altitude of almost 5,200 m, everyone feels the effects of the altitude, regardless of their physical fitness.

To be on the safe side:

• Acclimatize for at least 1–2 nights in Cusco.
• Drink plenty of water.
• Eat light, carbohydrate-rich meals.
• Take breaks during the ascent.
• Avoid alcohol the day before.

Descend immediately if you experience any of the following:

• Dizziness
• Nausea
• Severe headache
• Shortness of breath

Coca tea or coca leaves can alleviate the symptoms, but they are not a cure.

Reputable providers carry the following:

• Oxygen
• First aid kits
• Trained mountain guides
• Radio or satellite devices

Directions: What the hike feels like

From the summit area of Rainbow Mountain:

• You turn toward the signposted “Valle Rojo” trail.
• The trail follows a winding ridge with panoramic views.
• A short climb leads to Mirador del Valle Rojo, the best viewpoint.
• From here, the landscape opens up dramatically into a red amphitheater.

Depending on your tour guide, you can:

return via the same route or descend through the valley (a spectacular alternative route)
The entire detour usually adds 45 to 90 minutes to your day.
