There are four miles of paved road within the national park, connecting the park entrance with the Visitor Center, Dunes Parking Area/Picnic Area, Mosca Pass Trailhead, and PiƱon Flats Campground.
Visitors with a high-clearance 4WD vehicle may explore the Medano Pass Primitive Road, which goes along the edge of the dunefield then traverses a 10,000 ft (3,048 m) mountain pass to the Wet Mountain Valley. The road is typically open from mid-May through late November. Trailheads including Sand Ramp Trailhead and Medano Lake Trailhead are accessed from this road. Commercial Jeep tours of Medano Pass Primitive Road are available during warmer months.
Liberty Gate Trailhead is a backcountry trailhead providing access to the north side of the national park.
The newest free public EV charging station is located at Fort Garland Museum and Cultural Center, located 30 miles southeast of the national park on US 160. Visitors can learn about the multifaceted history of the San Luis Valley while charging their vehicle.
