Medano Lake is located 2 miles north of the Great Sand Dunes National Monument. Medano Creek originates high in the Sangre de Cristos and flows into the Great Sand Dunes National Monument. Access is by 4-wheel drive vehicles, either through the Monument or via Forest Road 559, off of Highway 69. Motor vehicles are prohibited on the trail from the road to Medano Lake. Fishing varies, but there are usually enough brook and rainbow trout to keep fishermen interested. Cutthroat, brook and rainbow trout live in the lake.
Medano Lake Trail begins just below Medano Pass. Starting in a stand of spruce-fir, the trail rises moderately as it follows Medano Creek to Medano Lake. Medano Creek and Medano Lake offer the visitor good fishing possibilities. Suitable campsites are available. A short hike to the ridge above Medano Lake provides the visitor with magnificent views of the Sand Dunes.
The road to the trail is very difficult and should only be attempted by high-clearance four-wheel-drive vehicles or hikers.
