Medeno Pass Road is a rough, Aprox. 22 miles, road connecting the Great Sand Dunes with the Wet Mountain Valley and Colorado State Highway 69. Passable only in the warmer months only with high-clearance 4-wheel drive vehicles and off road registered vehicles including dual sport bikes. This primitive road gives access to Medano Pass (elevation 10,040’) and Great Sand Dunes National Preserve. This road crosses areas of loose sand, traverses Medano Creek nine times, and passes through excellent habitat for bighorn sheep, Bear, Deer and Elk. Average driving time for the entire primitive road is about 2.5 – 3 hours.
A free air station is available near the south entrance to the road in warmer months between the hours of 7AM and 9PM if you air down. If you reduce pressure, you will need to reinflate using your own air compressor before driving over rocks in Medano Canyon. This road is only available to Highway registered vehicles as the Sand dunes is a National Park and does not allow ATVs and UTVs. The Medeno road can be very challenging with the possibility of mud, high water and mountain riding but it is worth the trip for an experienced rider for sure. Pack a lunch
