Located inside the Sand Flats Recreation area, Fins ‘n Thing is a great roller coaster ride on slick rock fins, offering spectacular views of the La Sal Mountains and the surrounding landscape of Moab. Fins is a shorter run, comprised of two trails. The first part of the trail weaves in and around several campsites and can only be run during the day (per park rules). The second section of Fins is longer and offers some extreme up/down action that’ll either have your inner child jumping with excitement or your butt clenched in terror. This is a Moab must for anyone who wants to experience slick rock at its best.
