You'll need a CO Parks and Wildlife pass to park a vehicle. Day passes are self-pay and cost $7 (cash-only).
Advanced riders may enjoy the challenges of big roots and lots of rocks, but most riders will have to walk long sections of the trail, though the park service may be slowly rebuilding it (already done at the far western end).
This trail seems to be going steeply up or down virtually all the time. You wander around aspen and pine forests with occasional openings, but never any big views.
Most riders (certainly intermediates and below) will find Mule Deer Trail Golden Gate State Park and others in the park more enjoyable.
