Button Rock Dam Access provides walk-in only access to Button Rock Preserve near Lyons, with a 60-vehicle parking lot (closed when full) open one hour before to one hour after sunset.

The preserve features a fully accessible creekside fishing pier near the entrance and gravel trails along North Saint Vrain Creek, though no boats, swimming, or dogs are permitted.

A Colorado fishing license/permit is required, with special permits needed for Ralph Price Reservoir access approximately 2 miles into the preserve.
