Grenadier Range Mountains

Tucked away in the San Juan Mountains lies the heart of the Weminuche Wilderness: the Grenadier Range. Forming an eight-mile arc from the Animas River to Vallecito Creek, the Grenadier Range is a treasured gem for mountaineers and winter athletes because of its sequestered location.

Any trip into the Grenadier Range will require at least a one-night backpacking trip. The range is 32 miles northeast of Durango, so trips require dedication, adequate planning, and proper gear. 

Should visitors find their way into the range, they will be richly rewarded with paramount views of the Colorado Rocky Mountains. 

Things to Do in the Grenadier Range Mountains


There are multiple opportunities for thru-hiking in the Grenadier Range. One of the best ways to see its entirety is to hike the 1.8-mile Cunningham Gulch Trail. At the trail’s end, thru-hikers can hook up with the Continental Divide Trail and eventually continue off the beaten path—following the peaks.


While there are no developed campsites in the area, dispersed camping is allowed in the region—provided that you stay on public lands. Be sure to bring ample supplies with you on your journey and to have a method for purifying water.
