It's largley unknown by non-locals. It's a unique area on BLM land with 20 to 30 miles of rolling desert singletrack - terrain like a very long BMX track, with various optional loops. No extended climbing. Not especially difficult but loads of fun. Ideal season is spring and fall.
Summer is too hot.
This is a great ride for riders of all abilities. For beginners it will be a good challenge and the more advanced riders can always challenge themselves to go more quickly. From Lion's Wilderness Park and complete the 30 mile loop. A good workout and fun trail. I use this trail system mostly when the Durango area is covered in deep snow.
