Within the Turtle Mountains Wilderness is located the Turtle Mountain National Natural Landmark an area of land recognized for its exceptional geological value and an area held in high spiritual value by the Native American Tribes of the Southwest. Mexican Hat Trail is a small portion of a greater trail which once linked centuries of travelers to the Colorado River. If the hike to the top of the trail doesn't appeal to you, an ADA compliant ramada and picnic table are available for day use and camping at the Lisa Dawn or Brown's Cabin developed campsites. Photographers love this area. In the spring cacti floral displays are bountiful within the surrounding area. History buffs practice black and white imagining, and if patience, wildlife will present the public with many photo opportunities
