This trail network is typical of what Colorado has to offer... a technical granny gear ascent up 1800+ ft on the Maverick trail with spectacular views of the surrounding Rocky mountains and wildlife. The downhills can get pretty gnarly as well with lots of rocks and log dropoffs. We didn't get to ride the entire network because we got caught in a thunderstorm, luckily we hid out in a cave on the Mustang trail until the storm passed. Pick up a map at the parking lot as there are several trails to explore!
From Denver, take 70W to Golden. White Ranch State Park is ~2miles north of Golden and ~17 miles south of Boulder on Hwy 93. Turn west (right if coming from Golden) onto W 56th Ave and follow the signs to the parking lot.
