White Ranch has a wide variety of trails, from really rocky cactus-lined tracks to wooden bridges. There are several great views of Golden, Denver, and the Front Range.
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.
