Ausangate Seven Lakes: A High-Andean Trekking Guide

The Seven Lakes route near Ausangate leads through one of the most dramatic high-altitude environments in the Cusco region. Glacial water, mineral colors, wetlands, alpaca herds and the presence of the sacred mountain create a landscape that feels immense and alive.

This is not a low-altitude nature walk. Cold, wind, intense ultraviolet radiation and limited oxygen make preparation essential.

Why Do the Lakes Have Different Colors?

Water color can be influenced by minerals, sediments, depth, light and reflections from the surrounding terrain. Depending on weather and viewing angle, visitors may notice turquoise, green, deep blue or reddish tones.

Photographs taken in strong sunlight can look different from what appears under cloud. The changing color is part of the natural experience.

The Main Challenge: High Elevation

Much of the route lies at very high altitude. Spend several days acclimatizing before departure and avoid placing this trek at the beginning of a Cusco itinerary.

• Walk slowly from the first minute.
• Drink water regularly.
• Protect exposed skin from sun and wind.
• Tell the guide immediately about symptoms.
• Be willing to shorten the route if conditions require it.

Life Around Ausangate

Quechua-speaking communities raise alpacas and llamas in this demanding environment. Herding, weaving and community organization are not staged attractions; they are part of daily life.

Ask before photographing people, homes or private activities. Purchase textiles directly when possible and avoid aggressive bargaining over work that may require days or weeks to produce.

Thermal Waters and Recovery

Some itineraries include community-managed thermal baths after the hike. Availability and operating conditions can change, so confirm what is included. Bring dry clothing and follow local rules about changing areas and waste.

What to Carry

• Warm base, mid and outer layers.
• Waterproof jacket and pants.
• Gloves, warm hat and sun hat.
• Sunglasses with ultraviolet protection.
• Water, snacks and personal medication.
• Trekking poles and reliable footwear.

Protecting Glacial Water

Do not enter the lakes, use soaps nearby or leave food waste. Wetlands are fragile and may take years to recover after being trampled. Remain on the route indicated by guides and community authorities.

To visit Ausangate responsibly is to recognize that the landscape is beautiful, inhabited and culturally significant at the same time.
