Best time to hike the Ausangate Trek

Table of Contents

The Ausangate Trek is one of Peru’s most spectacular multi-day hikes, taking adventurers through towering snow-capped peaks, turquoise glacial lakes, remote Andean villages, and mountain passes exceeding 5,000 meters (16,400 ft). Unlike the Inca Trail, this trek remains wild and less crowded, offering an authentic experience in the heart of the Peruvian Andes.

However, because of its high altitude and rapidly changing mountain weather, choosing the right time of year is essential. The season you choose will affect trail conditions, visibility, temperatures, camping comfort, and even your chances of enjoying the incredible scenery that makes Ausangate famous.

If you’re wondering when is the best time to hike the Ausangate Trek, this guide covers everything you need to know, including the weather by month, the differences between the dry and rainy seasons, and expert tips to help you plan your adventure.

When Is the Best Time to Hike the Ausangate Trek?

The best time to hike the Ausangate Trek depends on what you’re looking for. If you want the best weather, clear mountain views, and dry trails, plan your trek between May and September.

If you prefer fewer crowds while still enjoying good hiking conditions, April, May, September, and October are excellent choices.

The rainy season, from November to March, offers greener landscapes and quieter trails, but you should expect more rain and less predictable weather.

In the end, there isn’t a single perfect time to hike the Ausangate Trek. The right season depends on whether you prioritize weather, scenery, or a quieter experience.

Best Time to Visit Rainbow Mountain During the Ausangate Trek

Many Ausangate Trek itineraries include a visit to Rainbow Mountain (Vinicunca), making it possible to experience two of Peru’s most iconic landscapes in a single adventure.

If your priority is enjoying the best views, the ideal time to visit is between May and September. During the dry season, you’ll usually find clearer skies, better visibility, and drier trails, allowing Rainbow Mountain’s colorful mineral formations to stand out at their best.

If you prefer a quieter experience, consider hiking in April, May, September, or October. These shoulder-season months generally offer a good balance between favorable weather and fewer visitors, allowing you to enjoy the scenery without the larger crowds of the peak season.

No matter when you visit, combining the Ausangate Trek with Rainbow Mountain is one of the best ways to experience the breathtaking landscapes of the Peruvian Andes. For a more detailed guide on weather, altitude, and planning your visit, explore our complete Rainbow Mountain guide.
