North of Vernal and southeast of Manila in the Flaming Gorge National Recreation Area, the Swett Ranch Loop is a 6 mile horseback riding route on old forest roads through juniper, ponderosa, douglas and aspen forests with scenic views of Lake Fleming Gorge and Baretop Mountain.
To reach the horseback riding trailhead from Vernal, head north along US 191. One mile north of the junction with UT44 is the Greendale rest area. Park here. The trail begins at the east end of the rest stop. Head north along FS 157 and down the hill to a 3-way intersection. Take the right turn and head east toward the Swett Ranch. After about a mile, take the spur to the left and pedal the road for about 0.5 mile to the ranch. Spend some time here browsing. Back out on the main route, the road ahead soon splits. Take the route to the left, ride past a carsonite post and go through a cattle gate (please close behind).
Follow the blue diamonds on carsonite posts, staying left, and enjoy the downhill cruise. The trail soon narrows and enters a grove of aspen trees, crossing two small streams. At the upcoming “T” junction, turn left and climb the hill about 1.5 miles back to the routes beginning.
Overall, Swett Ranch Loop is the 12th most popular horse trail of all 25 horseback rides in Utah.
