The Bull Valley trail is a scenic connector between the Beef Basin loop road and the Imperial Valley trail. It also accesses a spur trail to the rim of Gypsum Canyon in the Glen Canyon Recreation Area. The difficulty is on the hard side of moderate, with several rock ledge obstacles that would be challenging but passable by stock 4x4s. Expansive views are found along this trail as you descend a series of terraces into the Imperial Valley.
This is a great connector trail in a larger overlanding loop through the Beef Basin area, allowing you to visit overlooks of Gypsum and Imperial Canyons and then go up Impossible Hill on the way out. There are no established campsites along this trail, but camping is allowed throughout the area, and campsites can be found along several spur roads.
