Difficulty

West of Highway 89, stock 4x4 will find deep washouts that require good tire placement and potentially some road-building skills. Lifted rigs will have no problems. Ninety percent of the erosion is located on the Highway 89 end of the trail between Stagg Tank and Old Grand Canyon Tank. From Old Grand Canyon Tank to Aso Ranch, this is a grade 3 trail. East of Highway 89 (towards O'Leary Loop), it's a grade 3 trail and has no obstacles of note because there are bypasses for all eroded areas on that side of the trail. Note: monsoon season can, and will, change the nature of this trail. There is evidence of serious erosion problems with multiple, almost washed away, culverts attempting to repair the erosion between Stagg Tank and OGC Tank.
