Colorado
Great Sand Dunes National Park Medano Creek
Point of Interest
Medano Creek flows only during late spring snowmelt (typically May-June), creating a rare mountain stream at 8,200 feet elevation alongside 750-foot sand dunes. The creek forms natural pools and shallow rapids perfect for cooling off after hiking the dunes. Piñon Flats Campground sits just upstream with 88 sites, flush toilets, and potable water — book ahead for summer weekends.
Access via paved road from Highway 150. Creek flow depends entirely on snowpack; call ahead in dry years. Sand gets everywhere — seal food containers and expect fine grit in your rig for weeks. Winds pick up most afternoons, turning the dunes into a sandblaster.
