Features -none-

Family Friendly Easy singletrack trail system.

Closed during the winter. No dogs.


The route ends up completing a 12 mile loop in Red Mountain Open Space. The loop is a non-technical ride with great views. The trail system is located about 30 miles north of Fort Collins so it does take some time to get to the trail.

Need to Know

There's no water at the trailhead so bring plenty to drink.


Start on the Sinking Sun to Rising Sun Connector which is an easy climb to get you going. From there, connect with Big Hole Wash Trail and continue the climb to the Cheyenne Rim Trail. Here you'll find a steady climb up to the top of the ridge. You'll follow this around through flowing prairie.

From the prairie, connect with the Ruby Wash Trail, which is a 2.5 mile descent through beautiful red soil and cliff walls. The upper section is an easy, switch-back descent down the side of the hill into the wash while the lower section follows the normally dry stream bed following the deep red canyon walls.
There is deep gravel when you're in the wash which can make the descent difficult in places.

Watch for the Big Hole Wash Trail, which you'll encounter at the stream. This was the hardest climb of the day due to the thick gravel. Much of this section I couldn't ride. Follow the Big Hole Wash Trail to the east, and then head back to your vehicle via the Sinking Sun Trail and the Rising Sun Trail.

Salt Lick Trail is my preferred trail for creating the loop.

Hiked this on Friday July 7th and we were swarmed by deer flies. Literally covered and bites everywhere. Should have been some warning. Had to go to urgent care. Do not recommend this hike Jul 10, 2017

Too bad you can't access the Wyoming portion from Wyoming... Cheyenne Rim is the best here, don't get caught riding uphill in the 'wash' trails... Aug 4, 2017
@Sam Miller: There are plans to provide access to that area from the Wyoming side. Unfortunately, funding for the project was taken off the recent Laramie County Sixth Penny sales tax ballot at the last minute, so there is currently no funding for it. However, negotiations are still ongoing with UPRR for a railroad crossing to get access from the Wyoming side. Oct 3, 2017
