Visitor levels at Great Sand Dunes are sitting at about average for May. The main trailheads and viewpoints will have some company, but nothing unmanageable. Temperatures are at 53°F with overcast conditions. Layers are a good idea, especially at higher elevations. The park service has posted 4 caution notices, mostly advisory, but worth reading before you go. Entry is $25 per vehicle, or free with an America the Beautiful pass.

Many off road capable vehicles are becoming stuck in soft sand between Castle Creek and Crossing One. Driving on the Medano Pass Primitive Road in this area is not advised.
During busy holiday weekends, many vehicles will be parking along side park roadways. For your safety and the safety of others, and access for emergency vehicles, all vehicles must be parked with ALL FOUR TIRES outside of the white line to ensure traffic lanes are open and clear. Please drive slowly and watch for pedestrians on roadway.
Speed limits are between 10 and 30 MPH in busy areas. However, slower speeds are required in areas with people walking along roadways and in congested parking areas. Please ensure the safety and welfare of park staff and fellow visitors by taking extra caution driving in the park.
The air compressor and tire filling station at the Amphitheater Parking Area is OPEN for the Season. It is still recommended that vehicle operators using the Medano Pass Primitive 4WD Road be prepared with their own portable air compressor before deflating tires in the area.
Speed limits for the park include 30 MPH near the park boundary and Great Sand Dunes Sign, and as low as 10 MPH near the Headquarters and Entrance Station. Speed limits are in place to protect park visitors, pedestrians, and wildlife in the park. Please drive carefully and responsibly.
Sand boarding and sand sled rentals are located in local communities surrounding the park. Visitors are encouraged to arrange rentals BEFORE coming to the park.
Due to the need for improvements in Piñon Flats Campground, sites can be reserved 3 months in advance beginning in 2026.
