A rugged mountain run that follows a tumbling creek through a narrow canyon, with steep walls rising on both sides. The sound of rushing water and glimpses of small cascades keep the climb lively, while the cool air from the creek offers relief on warm days. A tough but scenic stretch on the way to higher ground or to Ouray.

There is a little parking area for the Hermosa Creek Trail system, which is quite extensive. And if you want to stay overnigt: The is a beautiful campground next to the trailhead, the Lower Hermosa Campground. It does not get much more convenient than this!

Wow, what a great day on two wheels! The Hermosa Creek Trail is a must-do if you love challenging singletrails in remote areas. Bring plenty of water and a bunch of snacks. The trail is usually ridden as a shuttle ride. Just call Hermosa Tours the day before you want to ride this trail and check if they have seats available. The phone number and prices can be found here: https://hermosatours.net/Durango-bike-shuttle.html.

Hermosa Creek Trail runs through the Hermosa Creek Wilderness Area. It includes smooth climbs with beautiful views. The trailhead provides valuable information about the area and the trail itself (though the latter is hard to lose).
