Discover 7 Lakes Ausangate: Cusco Hiking Destination (2027 Guide)

Are you yearning for an authentic, uncrowded mountain adventure in Cusco? Look no further than the mesmerizing Ausangate 7 Lakes Hike (Full Day). Nestled beneath the sacred peaks of the Cordillera Vilcanota, this pristine circuit offers an extraordinary tapestry of shimmering turquoise waters, snow-capped glaciated summits, and restorative natural thermal hot springs.

1. Where Are the 7 Lakes Ausangate Located?

The 7 Lakes of Ausangate (Siete Lagunas de Ausangate) are located in the southeastern quadrant of the Cusco region, within the Quispicanchis Province (Ocongate district). The trailhead begins in the indigenous Quechua community of Pacchanta, situated approximately 120 kilometers (74 miles) from Cusco city at an elevation of 4,300 meters (14,108 ft) above sea level.

The trekking loop meanders between 4,200 m and 4,600 m (13,780 to 15,090 ft), circumambulating the base of majestic Mount Ausangate. The principal glacial lakes along the circuit include:

• Azul Cocha: A striking, deep navy-blue glacial lake reflecting jagged ridgelines.
• Otorongo Cocha: Named after the jaguar for its speckled shoreline contours and shifting green-blue hues.
• Puca Cocha (Red Lake): Infused with iron-rich sediment that produces rust-tinted reflections.
• Oqecocha: A serene high-mountain basin framed by rugged moraine banks.
• Alqacocha & Comercocha: Brilliant jade-green and turquoise waters fed by the hanging glaciers above.

2. Why Are the Lakes So Vibrantly Turquoise?

The signature neon-blue and emerald coloration of the Ausangate lakes is a natural geological marvel. As the massive glaciers of Mount Ausangate slowly grind against volcanic and metamorphic bedrock, they pulverize mineral-rich stones into microscopic particles known as rock flour (glacial silt).

During seasonal melt, this rock flour flows directly into the lakes. Because the mineral particles are extraordinarily light, they remain suspended in the water column rather than sinking. When high-altitude sunlight strikes the water, the suspended particles scatter the shorter wavelengths, creating the luminous, otherworldly turquoise tones captured by travel photographers worldwide.

3. Weather Conditions & Temperatures

Weather at 4,500 meters is famously dynamic. Hikers should be prepared for intense sun, chilly Andean gusts, and sudden weather shifts within the span of an hour:

4. Best Time to Hike the 7 Lakes Ausangate

The optimal window for trekking the 7 Lakes circuit is during Cusco’s dry winter season, running from May through September.

• June, July & August: The driest months with virtually zero rainfall, crystal-clear blue skies, and optimal reflections on the lakes. Night temperatures drop below freezing.
• May & September: Shoulder season months offering excellent trail conditions, pleasant hiking weather, and vibrant green meadows.
• November to March: The rainy season brings frequent afternoon showers, cloud cover, and occasional snow flurries at high passes, though the mountain slopes burst with blooming wildflowers.

5. How to Visit: Day Tours vs. Multi-Day Treks

Depending on your travel itinerary and physical conditioning, there are three primary ways to explore this region:

A. Full Day Guided Tour from Cusco (Most Popular)

Departs Cusco early morning (around 4:30 AM), drives 3 hours through Urcos and Ocongate to Pacchanta, embarks on the 5 to 6-hour circular hike past all 7 lagoons, and finishes with a restorative soak in the Pacchanta hot springs before returning to Cusco by 7:00 PM. Our guided Ausangate 7 Lakes Hike 1D includes private transport, oxygen support, hot meals, and certified native guides.

B. Extended Ausangate & Rainbow Mountain Treks

If you have several days, consider our Ausangate Trek + Rainbow Mountain (3D/2N) or the celebrated Llama Trek to Rainbow Mountain (4D/3N), which integrate the 7 lakes with dramatic alpine passes and Vinicunca.

7. Flora and Fauna Around Ausangate

Despite the rugged elevation above 4,300 meters, this alpine ecosystem teems with specialized Andean biodiversity:

• Camelids: Thousands of domestic alpacas and llamas graze peacefully along the bogs and wetlands (bofedales). Wild vicuñas can occasionally be spotted on higher scree slopes.
• Birdlife: Look out for Andean geese (huallatas), giant coots, puna ibises, and the majestic Andean Condor soaring on thermals above the cirques.
• Highland Flora: Golden Ichu grass blankets the hillsides, alongside resilient Queñua (Polylepis) dwarf forests and spongy cushion plants that act as natural water reservoirs.

8. Local Guide Recommendations & Preparation

1. Acclimatize in Cusco First: Spend at least 2 full days in Cusco (3,400 m) or the Sacred Valley (2,870 m) before hiking above 4,500 m. Review our Altitude Sickness Guide for symptoms and prevention.
2. Wear Proper Footwear: Sturdy, waterproof hiking boots with aggressive tread are essential for rocky moraines and loose scree. Check out our Trekking Poles Guide to protect your knees.
3. Pack for Both Sun & Freezing Wind: Dress in 3 breathable technical layers: base layer, warm fleece or down jacket, and a wind/waterproof outer shell. Don't forget sunscreen (SPF 50+), sunglasses, and a beanie.
4. Swimsuit & Towel: Keep a towel, sandals, and swimwear easily accessible in your daypack for the Pacchanta hot springs at the hike's conclusion.
