Thanks to the work of our facilities and patrol rangers, Great Sand Dunes was able to open the Medano Primitive Road on May 19th, 2025, all the way up to the Medano Pass. The road is currently open on Forest Road 559 so that four-wheel drive vehicles can cross over the Sangre de Cristo Mountains into the Wet Mountain Valley and San Isabel National Forest from Great Sand Dunes.
All vehicles need to be 4WD High Clearance with a 4L setting on the transfer case to cross safely. Side-by-sides, UTVs, and ATVs are prohibited west of Medano Pass within all areas of Great Sand Dunes National Park and Preserve.
See Go.nps.gov/Medano_Road for current conditions and trip planning information.
