Sand Flats Recreation Area (SFRA) is home to the trail that put Moab on the mountain biking map, the famous Slickrock Bike Trail.  Another popular bike trail, the Porcupine Rim Trail also leaves from SFRA.  Both trails feature steep inclines and descents, which offer technical challenges to the most experienced bikers.  Detailed maps of the Slickrock Bike Trail and the most popular jeep trails – Hell’s Revenge 4×4 Trail and Fins & Things 4×4 Trail, are downloadable on the maps page.  For the Porcupine Rim Trail, Porcupine  4×4 Trail and other trails, please refer to the visitors guide map.  Most of the trails are rated ‘difficult.’  All mechanized vehicles (motorized and non-motorized) must travel marked routes.There are NO open play areas in Sand Flats.  “Play areas” are considered places where users congregate, using the same section of trail or obstacle over and over, creating loops to return.  Consistent repeated use of obstacles on the trails causes high impact in these sections, degrading the trails to a point that they become impassable.  It also creates unsightly denuded areas or rubber marks on slickrock that can be seen for miles.Spring, fall and winter seasons are also perfect for exploration of the remarkable fins, domes and watercourses in Sand Flats by foot.  Hike on slickrock and in dry washes, avoid vegetation and cryptobiotic soils and enjoy the solitude that Sand Flats offers.
