Go to the sled city web site. They have a list of clubs including one in the Spings by Fort Carson. They will know the best and closeest areas. I'm not much help, I ride up north of I-70 highway mainly. I do know that it is not far to several areas from Fort Carson. The same site will give you a list of some of the better known areas, way too many places to unload and ride to learn about in 2 or three years. I've been riding Colorado for 15 and still find new places I have not riden before.
