Welcome to one of the deepest canyons in the world, a place of staggering landscapes and soaring condors. To truly experience its scale, you'll want to take a trek down into the valley, staying overnight in one of the simple, welcoming villages at the canyon's base. The real challenge is the steep, early morning hike back out, but the rewarding views and the unforgettable sight of the majestic Andean condors gliding on the morning thermals make every step worthwhile. Most treks take 2-3 days to fully appreciate the journey.
