MTB Ride starting at the first parking area just beyond the ranger station and park entrance. Began on trail 121, up to 120 which puts you out at Selkirk Lodge parking area. Then across the road to trail 130 up to the Big Springs picnic area. Cross the asphalt then on trail 130 again to the CCC Cabin. From there out Mt Kit Carson Rd up to the Vista House, (on asphalt), for lunch. Then back down to Mt Kit Carson Rd down to trail 110. Hop off on trail 100 across back to Selkirk Lodge parking. (note - this trail is very difficult to ride in the west to easterly direction). Out the cross country trails to Quartz Mtn Lookout. Back to the Selkirk Lodge parking lot, cross the road and jump on trail 100 again. (Good ride east to west). Followed it down to multiple trail interchange and then take trail 110 back down to the parking area.
