Roadside camping is permitted at 21 campsites in Great Sand Dunes National Preserve beginning 5.2 miles from where the road begins near Piñon Flats Campground. These designated sites are free of charge and first-come, first-served. All 21 sites fill on summer weekends. Passable only in the warmer months and only with high-clearance 4-wheel drive vehicles. This road crosses areas of deep sand, traverses Medano Creek nine times, and passes through excellent habitat for bighorn sheep.
The description, directions and fees are the National Park Service’s own words, from its record on Recreation.gov.

Gaps with no tint inside public land are private parcels, often old mining claims and homesteads. They are not open to the public.
Dashed clay lines on the base map are unpaved tracks from OpenStreetMap. They show what exists on the ground, not what is legal to drive.
Boundaries are approximate and land status changes. This map is a planning aid, not a survey or a statement of access. Confirm routes, closures and camping rules with the managing office.
