7. Cotahuasi Canyon – Peru
There are a couple of entries on this list from Peru, and Cotahuasi Canyon, which plummets to 11,598 feet (3,535 m) at its deepest point, is the first. The canyon was carved out between two mountain ranges, the Coropuna and the Solimana, by the Cotahuasi River.
The landscape surrounding Cotahuasi Canyon is both dramatic and remote – and if you want to visit, you’ll need to spend up to 12 hours on a bus getting there. Still, while this may be inconvenient for tourists, it isn’t such a bad thing from a conservation perspective.
