Characterized by crumbling Inca ruins, colonial towns, lush foothills, and the jutting, snow-capped peaks of the Andes, Peru’s Sacred Valley is a 60-mile (100-kilometer) stretch between Cusco and Machu Picchu. The area is a mecca for history buffs—the Agricultural Terraces of Moray and Ollantaytambo Ruins grant a glimpse into ancient Inca civilization—and also a playground for travelers with an appetite for adventure. Among the Sacred Valley's many things to do, you can go white-water rafting, rock climbing, or hiking to see the Urubamba River and the Salt Mines of Moray.
