Every now and then we come across a truly great overland trail and Medano Pass Primitive Road is one of them! It is a rough 22-mile trail connecting the Wet Mountain Valley and CO State highway 69 with Great Sand Dunes National Preserve. The trail feels like an adventure, climbing to Medano Pass at elevation 10,040’, crossing Medano Creek nine times and traversing areas of deep sand. It has many primitive camp locations as you get closer to the Preserve and if you want to drive it in a day, it will take between 2.5-3 hrs. Our advice is to take a couple of days and camp the first night along the solitude of the trail, exploring the Preserve and dunes the second day. 

Climbing up Medano Pass at 10,040′

The warmer months are the best times to go, as there will be snow closing the trail in the winter. Fall is spectacular with amazing color in the trees. We drove the trail in Fall and scored. We also explored the Great Sand Dunes in January and had snow on the dunes which was fantastic. At this time, the Medano Pass Road was closed and it was beautiful and Freezing!

Medano Pass Road Camping

There are 21 numbered primitive sites along the Medano Pass Road, each one being marked with a brown post and camping logo. These sites are free of charge and are first-come, first- served. It was completely empty when we were there in Fall, although apparently summer months and Holiday’s they fill fast. Access is only available late spring through Fall, due to snow conditions.
