There are some beautiful travertine falls off the Grand Canyon on the Havasupai Indian Res.

The water in Havasu Canyon contains a high concentration of limestone which gives it a strikingly beautiful turquoise color. Only a twelve mile hike from the trailhead, the campgrounds are located among a series of gorgeous waterfalls, and wading pools.
Camping, hiking and lodge. You can walk in, ride in, or take a helo.
