Twice as deep as the Grand Canyon but a fraction of the width, Colca Canyon cuts a dramatic scar across Peru's southern Andes. Located about 70 miles northwest of Arequipa, it’s one of the most visited natural attractions in Peru. People head to Colca for two main reasons: to watch Andean condors as they glide on the thermals close to the canyon walls, and to trek down to the canyon floor. Many tours combine both, creating a fascinating mix of wildlife spotting, cultural engagement and trekking.

The trek down into the canyon is comparatively leisurely, but be prepared for a gruelling trek back up. This is, after all, one of the deepest canyons in the world. If you are going all the way down, you’ll stay in one of the small villages dotted along the canyon floor. In some cases, you’ll find yourself near a thermal spring, the perfect place to relax while drinking a cold beer.
