The Ausangate and Rainbow Mountain Trek is one of the most impressive high-altitude adventures in Peru. Instead of visiting Rainbow Mountain on a short day trip from Cusco, this route takes you deep into the Andes, where glaciers, turquoise lakes, high mountain passes, alpaca herds, remote communities, and colorful valleys become part of the journey.
This Ausangate adventure combines the wild landscapes surrounding Ausangate Mountain with one of Peru’s most famous natural attractions: Rainbow Mountain, also known as Vinicunca.
Over four days, you’ll hike through remote Andean scenery, cross elevations above 5,000 meters, experience the silence of the mountains, and finally reach Rainbow Mountain after exploring much more of the region.
If you’re looking for more than a quick photo stop, the Ausangate and Rainbow Mountain Trek offers one of the most complete trekking experiences near Cusco.

Why Combine Ausangate and Rainbow Mountain?
Ausangate Mountain and Rainbow Mountain are often visited separately, but hiking them as part of the same route creates a completely different experience.
Rainbow Mountain is famous for its colorful mineral layers, while the Ausangate Trek is known for glaciers, high-altitude lakes, huge mountain landscapes, alpacas, and traditional Andean communities.
Combining both destinations allows you to experience the region gradually instead of arriving at Rainbow Mountain, taking a photograph, and returning immediately to Cusco.
During the trek, you’ll discover:
- Snow-covered mountains
- Turquoise glacial lakes
- High Andean valleys
- Alpacas, llamas, and vicuñas
- Remote Quechua communities
- Colorful mountains
- Rainbow Mountain
- Red Valley
- Views of the Vilcanota Mountain Range
Rainbow Mountain becomes one highlight of a much larger Ausangate adventure.

What Is the Ausangate and Rainbow Mountain Trek Like?
Every day on the trail introduces a different side of the Andes.
Unlike routes built around a single attraction, the Ausangate Rainbow Mountain Trek constantly changes. Mountains lead to valleys, valleys open onto glacial lakes, and high passes reveal new views of the Vilcanota Mountain Range.
Here is what you can expect from a typical 4-day itinerary.
Day 1: Enter the Ausangate Region
Your journey begins with an early departure from Cusco toward the high Andes.
As you leave the city behind, the scenery changes quickly. Agricultural valleys gradually give way to open grasslands and towering mountains.
The first section of the hike allows you to begin adapting to the terrain while enjoying your first views of Ausangate Mountain.
Along the way, you’ll likely see:
- Alpacas and llamas
- Traditional Andean communities
- Open mountain valleys
- Snow-covered peaks
- High-altitude landscapes
You’ll spend your first night surrounded by the mountains, far from the noise of the city.
Day 2: High Mountain Passes and Glacial Lakes
The second day brings you deeper into the Ausangate trekking route.
You’ll climb through high mountain passes surrounded by glaciers and turquoise lakes. The altitude makes the hiking more demanding, but the landscape becomes increasingly impressive.
Some of the day’s highlights can include:
- Glacial lagoons
- Views of Ausangate
- High-altitude passes
- Alpaca herds
- Remote valleys
- Panoramic views of the Andes
This is where the scale of the Ausangate region becomes clear.
The mountains dominate the horizon, and there are long sections of trail where very little separates you from the surrounding wilderness.
Day 3: Approaching Rainbow Mountain
As the route continues, the colors of the landscape begin to change.
Brown, red, yellow, green, and ochre tones appear across the mountains as you move closer to Rainbow Mountain Peru.
Unlike visitors arriving on a standard day tour, trekkers approach Vinicunca after several days in the mountains.
This creates a very different experience.
Instead of Rainbow Mountain being the entire journey, it becomes the natural continuation of your trek through Ausangate.
Depending on the route and departure time, you may also have opportunities to experience the area during quieter periods of the day.
Day 4: Rainbow Mountain and Red Valley
The final day brings one of the most anticipated moments of the Ausangate and Rainbow Mountain Trek.
You wake early and continue toward Rainbow Mountain, or Vinicunca, one of the most recognizable landscapes in Peru.
From the viewpoint, you’ll see the mountain’s famous mineral-colored slopes as well as wide views across the surrounding Andes.
The adventure can also continue toward Red Valley, where deep red mountains and open high-altitude terrain create another completely different landscape.
After exploring the area, you’ll begin your descent and eventually return toward Cusco.
It’s the end of four days of hiking, but also the culmination of a much larger journey through the Ausangate region.
How Difficult Is the Ausangate and Rainbow Mountain Trek?
The Ausangate and Rainbow Mountain Trek is considered moderate to challenging, mainly because of its altitude.
The route does not usually require technical climbing skills, but trekkers spend much of the journey above 4,000 meters / 13,123 feet and can cross elevations above 5,000 meters / 16,404 feet.
At these elevations, even relatively simple climbs can feel demanding.
Expect:
- Long hiking days
- Steep ascents and descents
- Thin air
- Cold temperatures
- Strong sunlight
- Rapid weather changes
Good physical conditioning helps, but acclimatization is just as important.
Acclimatization Before the Ausangate Trek
Spending time at altitude before starting your trek is highly recommended.
Try to spend at least 2–3 days in Cusco or another high-altitude destination before beginning your Ausangate adventure.
During this period:
- Drink plenty of water
- Avoid intense exercise on your first day
- Eat light but nutritious meals
- Sleep properly
- Take short acclimatization walks
- Listen to your body
Being physically fit does not guarantee immunity from altitude sickness, so gradual acclimatization remains important.
What Makes the Ausangate Trek Special?
The Ausangate region feels very different from many of Peru’s most famous trekking destinations.
Here, the main attraction isn’t archaeological ruins.
It’s the landscape itself.
The route passes through an environment shaped by glaciers, mountains, lakes, high grasslands, and centuries of life in the Andes.
Ausangate Mountain
Standing at approximately 6,384 meters / 20,945 feet, Ausangate is one of Peru’s highest mountains and an important sacred mountain, or Apu, for communities in the Cusco region.
Its glaciers and snow-covered slopes dominate much of the trek.
Glacial Lakes
The region surrounding Ausangate contains spectacular high-altitude lakes in shades of turquoise, blue and green.
These lagoons are among the most memorable landscapes along the trail.
Andean Wildlife
Hikers regularly encounter animals adapted to life at high elevation, including:
- Alpacas
- Llamas
- Vicuñas
- Andean birds
Large herds of alpacas are especially characteristic of this part of the Andes.
Local Andean Communities
The Ausangate region is also home to remote Quechua communities where traditional clothing, agriculture and alpaca herding remain part of everyday life.
Traveling through these areas adds an important cultural dimension to the trek.
Rainbow Mountain: The Finale of the Adventure
Rainbow Mountain is often visited as a separate day tour from Cusco.
However, reaching Vinicunca through the Ausangate trekking route provides more context.
You’ve already walked through glacial valleys, crossed high mountain passes and watched the landscape gradually change color.
Rainbow Mountain isn’t an isolated attraction anymore.
It becomes part of the wider geography of the Vilcanota Mountain Range.
That is one of the main reasons travelers choose the Ausangate and Rainbow Mountain Trek instead of visiting both destinations separately.

Tips for Your Ausangate Adventure
A few simple decisions can make your trek considerably more comfortable.
Walk at Your Own Pace
High-altitude trekking isn’t about speed.
Maintain a steady pace, especially when climbing mountain passes.
Stay Hydrated
You may become dehydrated quickly at high elevation, even when temperatures are cold.
Drink water regularly instead of waiting until you’re thirsty.
Eat Regularly
Altitude can reduce appetite, but your body still requires energy.
Eat small meals and snacks throughout the trek.
Protect Yourself From the Sun
UV radiation becomes stronger at high altitude.
Use sunscreen, sunglasses and a hat even when the weather feels cold.
Prepare for Cold Nights
Temperatures can fall rapidly after sunset.
Keep thermal clothing and warm layers easily accessible.
Respect Local Communities
Remember that the trail passes through landscapes where people live and work.
Respect private property, local traditions and the natural environment throughout your journey.
