Greenbelt Plateau Area Dog Regulations Map
Learn about bringing your dog to OSMP. 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.
Dogs must be leashed seasonally along the Greenbelt Plateau Trail to protect grassland ground-nesting birds.
Horses are allowed on most trails. Off-trail riding is allowed in the Southern Grasslands Habitat Conservation Area (HCA) with an off-trail permit. Off-trail riding is discouraged to protect rare plants and wildlife habitat. Learn more about riding your horse on OSMP.
There is an abundance of raptors, mule deer and coyotes. The surrounding land is designated as a grassland management area to protect grassland plant and animal communities. Many birds, such as killdeers, meadowlarks and vesper sparrows, nest on the ground here during spring and summer.
