Monument Valley Navajo Tribal Park is one of the most picturesque areas of the southwestern desert. The red sandstone buttes combine with the deep blue sky and open horizon. This area of Northern Arizona and Utah is in the middle of the Navajo Nation Reservation. There are various trails and guided tours as well as campsites right in the park, if your more of a hotel person than a sleeping bag person the website lists places to stay within 100 miles.
You can also stay with the Navajo Indians for one night. They welcome you with steak cooked over an open fire and a night under the stars. One not to miss!
