Middle Fenceline is a moderate access route between Sand Dune Way and Water Tank Road and is commonly used as an exit route from Milts Mile. The trail is extremely sandy, with large dunes along the east side. Users must negotiate occasional slickrock ledges under 12" and periodic protruding rock. Navigation from Milts Mile to the Water Tanks is simple as you follow along the south side of the fence. East of Milts Mile, navigation can be complicated and changes from time to time due to shifting sands. Traction can sometimes be difficult, but this trail suits any stock high clearance vehicle with aired-down tires.
About Sand Mountain
Sand Mountain is an extremely unique parcel of public land. Designated as an Open OHV Area, riders are free to make their own trails. Due to this, many of the long-established named trail routes have several variations that can take easier or more challenging routes through the intended trail. The GPX track for this trail helps you navigate the area, but various lines, bypasses, and additional obstacles may exist along the way. Riders are encouraged to stay on existing trails and not unnecessarily drive over or destroy vegetation.
Fees
Riding on Sand Mountain is entirely free. However, there are multiple entry/exit points for the area, including "the tunnel," which connects Sand Hollow State Park to the open OHV area. Any entry into the boundaries of Sand Hollow State Park requires a Utah State Park Pass.
Requirements
When operating on Sand Mountain, users must attach an orange or red safety flag to the vehicle, rising at least 8 feet off the ground.
