Part of the spectacular Vilcanota Mountain Range, Mount Ausangate towers at a whopping 6,384 meters above sea level, making it the fifth-highest peak in Peru. For centuries, this sacred Apu (mountain spirit) has held deep spiritual significance for the people of the Andes. Every year, a week before Corpus Christi, thousands of pilgrims journey to its glaciated slopes for the ancient Qoyllur Ritti festival.
The local Chillca community, primarily llama and alpaca herders, are the traditional keepers of Ausangate. More than just a challenging hike, this trek offers a profound opportunity to connect with an ancient way of life in one of the most remote corners of the Andes.
Getting to Ausangate
Currently, there are two primary ways to reach the Ausangate trailhead:
Option 1: The Independent Route (Best for experienced trekkers)
If you are independent and budget-conscious, you can reach the trail using local public transport:
- Step 1: Catch a local bus from Cusco to the small town of Tinki (approximately a 3-hour journey).
- Step 2: From Tinki, take a second local bus or colectivo (about 3 hours) to the village of Pacchanta, where most of the classic circuit trails begin and end.
Option 2: Go with a Professional Tour Operator (Recommended)
If you prefer to bypass the logistics of rural bus schedules, language barriers, and coordinating heavy gear transport, booking an organized trek with a licensed agency is your best bet. They will handle private transport from your hotel straight to the trailhead, along with providing guides, chefs, and pack horses.
How Difficult is the Ausangate Trek?
The physical terrain of the Ausangate trek features mostly gradual ascents and wide alpine valleys rather than the steep, relentless stone steps found on the Inca Trail. However, it is widely considered a difficult trek for one specific reason: the elevation.
The trail never drops below 4,000 meters, and you will cross multiple high passes exceeding 5,000 meters.
Pro-Tip: Do not bring your main luggage on the trail. Pack only what you need in your daypack and duffel. Reputable hotels in Cusco or your tour operator will happily store your large suitcases for free while you are trekking.
Choosing Your Route
Because the Vilcanota range spans everything from day-trip landmarks to vast alpine circuits, you can experience this region across several different timeframes. Whether you just want a quick peek at the colorful peaks or a deep wilderness immersion, there is an itinerary tailored to your schedule:
- 1-Day Rainbow Mountain Trek: The ultimate time-saver. This fast-paced day trip from Cusco takes you straight to the iconic 5,020-meter ridge of Vinicunca (Rainbow Mountain) and back in a single day.
- 2-Day Rainbow Mountain Trek: A fantastic weekend option that lets you beat the day-trip crowds. You will hike to Rainbow Mountain, visit the striking Red Valley, and camp under the stars away from the busy tourist rush.
- 2-Day Ausangate Trek: A short but intensive alpine getaway. This route bypasses Rainbow Mountain to focus strictly on the dramatic, jagged glaciers and thermal hot springs of the classic Ausangate trailhead.
- 3-Day Ausangate Wilderness Trek: A balanced mid-length option. This route takes you deep into the alpine scenery, showcasing breathtaking mountain passes and the region’s signature turquoise glacial lagoons.
- 4-Day Mini Ausangate Circuit: Often called the “Mini Ausangate,” this condensed loop hits the classic heavy-hitters. It combines the raw glacial scenery of Mount Ausangate with a crossing to Rainbow Mountain for hikers on a tighter schedule.
- 6-Day Full Ausangate & Rainbow Mountain Circuit: The definitive Andean trekking experience. This multi-day expedition allows you to complete the grand loop around the sacred massif, conquer multiple passes above 5,000 meters, see the stunning Red Valley, and link directly to Rainbow Mountain.
Ausangate vs. Other Regional Treks
Unlike the Salkantay, Lares, or classic Inca Trail, the Ausangate trek does not lead to Machu Picchu, nor does it connect to the town of Aguas Calientes.
Instead, it offers distinct advantages:
- No Permits Required: You do not need to book months in advance to secure a spot.
- Crowd-Free Trails: The multi-day loops remain genuinely off the beaten path, offering true wilderness solitude.
- The Rainbow Mountain Link: It is the only multi-day wilderness trek in the region that allows you to hike directly to Rainbow Mountain on foot, arriving early in the morning before the massive fleets of day-trip buses arrive from Cusco.
Rainbow Mountain & The Red Valley
For many, the opportunity to see these geological wonders in a single journey is the main draw of the region.
Rainbow Mountain (Vinicunca)
Sitting at an astonishing 5,020 meters above sea level, Rainbow Mountain is famous for its vibrant, multi-colored mineral stripes.
- The Hike: From the standard approach, the trail is relatively short (around 4.4 km each way) with a gradual incline until the final, steep push to the viewing ridge.
- The Reality Check: While a 500-meter elevation gain sounds simple at sea level, doing it above 5,000 meters makes your lungs work twice as hard. Pace yourself, keep your breathing deep and rhythmic, and rest before the final steep section.
The Red Valley
If Rainbow Mountain looks like a painting, the neighboring Red Valley looks like the surface of Mars. The intense, iron-rich crimson earth contrasts brilliantly against the blue Andean sky.
Located just a 45-minute walk from the Rainbow Mountain summit, this valley is a breath of fresh air for hikers seeking quiet beauty. Because it requires a bit of extra hiking, only 5% to 10% of the daily crowds bother to visit, leaving you with wide-open, tranquil vistas.
Mastering the Altitude
Altitude sickness (known locally as soroche) is a serious consideration when hiking in the Vilcanota range.
What is Altitude Sickness?
As you ascend, the atmospheric pressure drops, meaning there are fewer oxygen molecules per breath. How your body reacts to this change is entirely personal and unrelated to your baseline physical fitness.
- Common Symptoms: Mild headache, slight nausea, fatigue, dizziness, and loss of appetite.
- Red Flags: If you experience severe shortness of breath (even while resting) or confusion, you must descend immediately and seek medical attention.
Prevention & Remedies
- Acclimatize First: Spend at least 3 to 4 days in Cusco (3,400m) or the Sacred Valley (2,870m) before starting the trek. Use this time to take easy day trips or complete shorter, lower-altitude day hikes.
- Hydrate Constantly: The high-altitude air is incredibly dry. Drink plenty of water and electrolyte solutions throughout the day and night.
- Eat Light & Skip the Alcohol: Your digestive system slows down at high altitudes on your first few days, so heavy meals and alcohol can exacerbate symptoms.
- Go Traditional: Drink hot coca tea (mate de coca) or chew raw coca leaves. The indigenous people of the Andes have used this natural remedy for millennia to increase oxygen uptake and alleviate fatigue.
- Western Medicine: You can readily purchase altitude pills (such as Acetazolamide/Diamox or local brands like Sorojchi Pills) over the counter at pharmacies in Cusco. If you are trekking with an agency, ensure they carry emergency oxygen tanks.
Essential Packing List
Temperatures on the Ausangate circuit can plummet well below freezing at night, while the daytime tropical sun can be intense. Layering is key.
Clothing & Gear
- High-quality down jacket or heavy fleece
- Thermal base layers (tops and bottoms)..
- Waterproof rain jacket and windproof trousers.
- Warm beanie, gloves, and a wide-brimmed sun hat.
- UV-protection sunglasses and high-SPF sunscreen.
- Broken-in waterproof trekking boots.
Logistics & Electronics
- Sturdy trekking poles (essential for saving your knees on steep gravel descents).
- Reusable water bottle and a reliable water filter or iodine purification tablets.
- Sturdy backpack with a waterproof rain cover.
- Camera with extra batteries (cold temperatures drain battery life rapidly).
- Plenty of high-energy snacks (nuts, chocolate, energy bars).
- If trekking independently: A certified 4-season tent, a cold-weather sleeping bag (rated to at least -10°C), a reliable camping stove, and a comprehensive first-aid kit.
Are you ready to experience one of the world’s premier alpine wilderness treks? Planning ahead and respecting the altitude will ensure your journey around sacred Mount Ausangate is an unforgettable Andean adventure.
