Learn about bringing your dog to OSMP. Dog control requirements vary from trail to trail, so carefully watch for dog regulation signs at trailheads and trail intersections. On most OSMP trails in this area, dogs must be on a hand-held leash at all times unless they meet the voice and sight control standard and display a City of Boulder Voice and Sight tag. Dog excrement removal is required by law. A dog station is available to aid in the collection of dog excrement.
Horses are allowed on most trails. On-trail riding is encouraged to protect rare plants and wildlife habitat. Learn more about riding your horse on OSMP.
