Great network of singletrack, technical, ledge/bench, downhill singletrack with a playground too. Includes Widowmaker Hill, Andy's Loop, Eagle Trail, Eagle View, Ribbon Trail, Tabeguche Trail, etc. This is a great network in the Grand Jct. area.
From HWY 50 in Grand Junction, take CO HWY 340 south across the Colorado River to Monument Road. Take a left on Monument Rd. and go for 2 miles and the parking lot will be on your left.
