South Canyon includes wildlife habitat. In general, if you see wildlife give them plenty of space and do not approach. In addition, at the request of the Colorado Department of Parks and Wildlife, dogs are not permitted on or around the South Canyon trails.
In Glenwood Springs, the Wulfsohn, Grandstaff and Forest Hollow trails are popular dog friendly areas. In Carbondale, Red Hill and the BLM trails on Prince Creek allow dogs.
Enjoy the trails, but please do not bring your dog to South Canyon.
