Trails on the City of Boulder Open Space and Mountain Parks are organized in four regions; North (N), South (S), East (E) and West (W). Each region has a Trail Study Area or TSA. Click to link to the PDF of trail study areas.

The Trailhead Leash Program requires dog guardians to leash their dogs upon exiting their vehicle at all OSMP trailheads, and in the area of the trailheads. See the trailhead leashing policy.
FIDOS encourages all dog guardians to adhere to the Voice and Sight regulations when out on V & S trails. Poor compliance to Voice and Sight regulations can lead to trail closures and further restrictions on dog access in open space.
