Get immersed head to toe-hair in the land of the Incas on this seven-day, hostel-based adventure high up in the Andes. Explore deep into Cusco on an insider's tour of the city's markets, cobblestone streets, and eye-popping plazas before heading into the Sacred Valley. Make some stops at lesser-visited (but equally awesome) Inca ruins, then hike up to a spectacular waterfall. Next, hop on the train to Machu Picchu for a guided tour of these legendary mountaintop ruins. After your life has been changed forever, head back to Cusco for more bucket-list optional activities like trekking to Rainbow Mountain.
