Dogs at Great Sand Dunes National Park
Great Sand Dunes is one of the more dog-friendly national parks, but pets are still limited to specific areas and must stay leashed.
Great Sand Dunes National Park CO (West) Dog Policy
Great Sand Dunes allows leashed dogs in more places than many national parks, including parts of the main dune area, Piñon Flats Campground, Mosca Pass Trail, Dunes Overlook Trail, and along Medano Pass Primitive Road. Restrictions still apply in backcountry and inside buildings.
Pets are permitted in Great Sand Dunes National Preserve, along Medano Pass Primitive Road, on Liberty Road, in the northwest corner of the national park, and in the main day-use area of the dunefield up to the first high ridge. Summer sand can reach about 150°F, so early morning and evening are the safest times for dogs on the dunes. Wildlife encounters are also a concern, so keep dogs close and under control.

Start early or go near sunset if you plan to walk with your dog on the sand. Great Sand Dunes warns that summer sand temperatures can reach about 150°F from late morning through late afternoon, which can burn paws quickly. Bring more water than you think you need, plus a collapsible bowl and paw protection if your dog is sensitive to heat. Keep your dog leashed and close at all times, especially around wildlife; the park notes risks from deer, coyotes, badgers, porcupines, bears, and mountain lions. Never leave your dog unattended in a vehicle, campsite, or tied to an object. If you camp at Piñon Flats or along Medano Pass Primitive Road, store food securely and do not leave pet food out, since it can attract bears and other animals. Finally, know the boundary rules before you head out: dogs can enjoy the main dune day-use area only up to the first high ridge, but they are not allowed in the dune backcountry, on Sand Ramp Trail, or inside park buildings.
