This is a mountain bike trail that was entirely built and maintained by mountain bikers. Biking, running, and hiking are all allowed in any direction with the right of way given to biking. No horses or motorized vehicles. Do not ride when muddy. Pack it in, Pack it out.
Palo Duro Lake, north of Spearman, is home to approximately 13 miles of singletrack. The trail is 95% singletrack and winds in and out of the caliche canyons that surround Palo Duro Lake.
The trail is very loose for the most part (especially during dry conditions) which can make for slipping feet and tough climbs/descents. This trail has been continuously added to and modified over the last decade.
