Havasu Canyon

One of the Grand Canyon's true treasures, this is a hidden valley with four stunning, spring-fed waterfalls and inviting azure swimming holes in the heart of the Havasupai Reservation. Because the falls lie 16km (10mi) below the rim, most trips are combined with a stay at either Havasu Lodge in Supai (the only village within the Grand Canyon) or at the nearby campground. For a spot at Havasu Campground you need to book six months to a year ahead.

Parts of the canyon floor, as well as the rock underneath the waterfalls and pools, are made up of limestone deposited by flowing water. These limestone deposits are known as travertine, which gives the famous blue-green water its otherworldly hue.
