Current Level of Medano Creek
From Great Sand Dunes, the Medano Pass Road crosses Medano Creek nine times on its way to Medano Pass. See the current cubic feet per second (cfs) flow of Medano Creek (available spring through fall). Creek flow is typically highest at dawn, and lowest in late afternoon. Peak flow for an average season is about 40 cfs (cubic feet per second), typically occuring in late May and early June. The current cfs flow indicates the level of the creek relative to average peak flow of 40 cfs.
Medano Pass Driving Season
The road remains fully open through the end of the fourth rifle hunting season in late November - if weather conditions allow. The road fully reopens when weather and road conditions allow, typically in mid-to-late May.

Roadside camping is permitted only at 21 numbered campsites in Great Sand Dunes National Preserve beginning 5.2 miles from where the road begins near Piñon Flats Campground. These sites are indicated with a brown post and camping symbol, and are numbered by approximate road mileage from the Park/Preserve boundary to Medano Pass. Numbers in parentheses are approximate road mileage from Medano Pass down to the Preserve/Park boundary. Roadside car camping is only permitted in designated sites in the national preserve. Vehicle access to these sites is only available late spring through fall, depending on snow, creek, and road conditions.
These designated sites are free of charge and first-come, first-served. All 21 sites fill on summer holiday weekends, and often on other summer weekends.
Camping Regulations for Medano Road Campsites
Fat bikes (mountain bikes with extra wide tires for sand) are permitted on the Medano Pass Primitive Road, both for day use and for overnight camping in Medano Canyon. Check current sand conditions (above on this page) before riding; if sand gets too soft and dry, travel may not be possible. Bikes are not permitted off-road.
You will be sharing the road with vehicles, some traveling at higher speeds in order to make it through sandy sections. For your safety, listen and watch carefully for vehicles as you ride.
For visitors that do not have a 4WD vehicle but would like to experience the Medano Road, there are companies that rent Jeeps and/or provide Jeep tours.
