Medano Pass Primitive Road — Great Sand Dunes to Westcliffe via Medano Pass
Drive the back door of the Great Sand Dunes
Most people look at the Great Sand Dunes from the parking lot. Medano Pass lets you drive around the back of them. The road leaves the park’s Point of No Return and runs up Medano Creek, and the first few miles are loose sand that eats tires. Air down early. You cross the braided creek about ten times, with the water spread wide and shallow in some spots and cutting deep in others. Past the park boundary the track hardens into rocky two-track and climbs through aspen and ponderosa to Medano Pass at 9,953 ft. From there you drop east through the Sangre de Cristo Mountains and come out on Colorado 69 near Westcliffe.
This is a Moderate drive if you know sand and a hard one if you don’t. Stock high-clearance 4WD works, but bring a recovery strap, a shovel, traction boards and a tire deflator with a compressor. Two-wheel-drive and low-clearance rigs get stuck here every summer. Spring runoff makes the crossings deeper, so late June through September is the safe window, and afternoon storms can swell the creek fast. There is no fuel or water on the route, and cell service is dead. Camping is in designated roadside sites only, with a backcountry permit from the NPS. You get big mountain views, dunes at sunset and almost no crowd once you pass the pass. Have a dirty day.

Frequently asked questions
Can a stock 4Runner or Tacoma do Medano Pass?
Yes, if it's 4WD with real high clearance and you air down. The soft sand and creek crossings stop AWD crossovers and low-clearance rigs, not capable stock trucks. Lockers aren't needed, but low-range helps in the deep sand.
When is Medano Pass open, and is it passable in winter?
Late June through September is the reliable window. Spring snowmelt makes Medano Creek deep and the crossings sketchy, and snow lingers on the upper pass. Check with Great Sand Dunes for current road status before you go, since closures happen.
Do I need a permit or pay a fee to drive Medano Pass?
You pay the Great Sand Dunes entrance fee to enter the park side. Camping in the park's roadside sites requires a permit from the visitor center. Dispersed camping in San Isabel National Forest outside the park boundary doesn't need one. Fees change, so confirm at nps.gov/grsa.
What's the hardest part of the Medano Pass road?
The soft sand and the dozen or so Medano Creek crossings in the park section. Most people get stuck by running full tire pressure, so drop to roughly 15-20 psi, keep momentum, and don't stop in the deep stuff. Bring a shovel, traction boards, and a compressor to air back up.
Is there cell service or gas on Medano Pass?
There's no cell service on the route and no fuel. Fill up before you commit, and carry a paper map or offline maps, recovery gear, and extra water. Westcliffe is the nearest town, and you're on your own in between.
