May is the beginning of winter in Peru, which means mostly sunny skies and relatively few crowds, with visitor numbers peaking a few months later in July and August.
The Inca Trail to Machu Picchu is Peru’s most iconic trek, but the country offers plenty of other opportunities to get outside and get active. Swaths of Amazon jungle, towering mountains and over 3,000 kilometers of Pacific coastline serve as the backdrop for surfing, hiking, biking, wildlife-watching and more. Go white-water rafting through the rivers of Colca and Cotahuasi canyons, mountain bike in the Callejón de Huaylas or hike along one of the lesser-known trails in the Sacred Valley.
