Trail shared by Stuart Black

A long, easy climb on well-designed singletrack followed by a great, fast descent.

Features -none-


This loop uses several different trails along the Colorado/Wyoming border in an almost wilderness setting. The early part of the loop is classic high plains riding with gently, albeit sandy, climbs.

The easy climb saves your energy for a long twisting descent back to your car. Be sure to stop and enjoy the views from the top of Cheyenne Rim Trail.

Need to Know

This is a long way from anything. Bring lots of water, sunscreen, and food. Exercise caution while riding as help could be a long way away. Cattle are present on the trail, and the area is rattlesnake territory so be aware.


This route makes a long loop of existing trails, heading counterclockwise along Pronghorn Loop, Pronghorn Loop to Mahogany Loop Connector, Mahogany Loop, Canyon Trail, and Cheyenne Rim Trail

The trails climb on relatively smooth and easy tread. There is some sand on the Canyon Trail but it is relatively short. Once you reach Cheyenne Rim Trail, the terrain becomes more challenging and technical with lots of rocks and fast descents and a few substantial climbs. It's mostly downhill but has some surprises. Watch for teepee rings and fire rings at the top of Cheyenne Rim Trail.

There are numerous loops that can extend this long ride even further if you wish.

History & Background

The area has been home to humans for over 20,000 years as evidenced by Folsom culture finds at the Lindenmeier site (northernmost parking lot off the Mahogany Loop to Canyon Trail Connector).
