Medano Pass Primitive Road

The terrain is quite diverse and challenging. You'll encounter significant stretches of deep, soft sand, especially on the western side within Great Sand Dunes National Park, which can make riding very difficult and may require walking your bike. Beyond the first mile from the southern entrance, standard mountain bikes often struggle. The road also features rocky sections and numerous crossings of Medano Creek (up to nine times). While generally rated as moderate, the deep sand and creek crossings significantly increase the difficulty. You may also find steep and rocky portions as you climb towards Medano Pass.

Yes, for much of the route, especially beyond the first mile from the southern entrance, a fat bike (a mountain bike with extra-wide tires) is highly recommended due to the deep, soft sand. Standard mountain bikes may struggle or require you to push your bike through many sections.

Herard (13,297') and the dunes. The area is also known for excellent bighorn sheep habitat. The route itself is historic, likely used by Zebulon Pike in 1807, and traverses the Sangre de Cristo Mountains. You'll also pass through Medano Pass.
