Sandboarding, sledding, and skiing are permitted anywhere on the dunefield away from vegetated areas. From the main Dunes Parking Area, it's a minimum 0.7 mile (1km) hike to get to the small or medium-sized slopes; the top of the first high ridge is 1.25 miles. Smaller slopes at the base are fine for young children, while teens and adults may prefer longer slopes near the top of the first high ridge of dunes.
