Deep within the San Rafael Swell region lies the Mexican Hat Wilderness, where access is limited to foot traffic. However, one trail, Lockhart Wash, offers an easement, allowing motorized travel into the wilderness before reaching the San Rafael River. The trail once traveled to the river edge, but now erosion has closed the final mile to the river. The trail has one nice camping area with distant views of the sandstone cliffs to the north. There is room for a couple of vehicles with tents. The route becomes rougher the further you travel. It's a bumpy two-track, without obstacles, and passable in high-clearance stock 4x4s. It is imperative that users remain on the established trail, as both sides of the road are wilderness.
