Big Al Trail

Big Al Trail (630) is handicapped accessible and offers spectacular views of the West Mancos River Valley and the La Plata Mountains with the visually prominent Mount Hesperus. The trail is a wide, graded, fine-gravel trail, passing through ponderosa pine, oak and aspen stands to a large wood-planked viewing platform perched on the rim of the West Mancos Canyon. The grade on the Big Al Trail never exceeds 8%, keeping the trail within the ADA maximum allowable grade of 12.5%, and there are benches located every 500 feet, making this path ideal for wheelchair users, persons with walkers, or anyone with reduced mobility. Tiny meadows break up the aspen forest and the trail is flecked with colorful wildflowers in every direction.

The trail takes its name from a local Forest Service employee, Al Lorentzen, who was injured while fighting a fire near Yellowstone National Park in 1988. Al is now a wheelchair user and the trail that bears his name is fully ADA accessible from trailhead to observation platform.

Please note, horses, mountain bikes and motorized vehicles are not allowed.
