Roxborough State Park near Littleton is famous for its tilted red-rock formations that rise from the foothills like giant fins. Designated a National Natural Landmark, the park offers some of the most dramatic scenery near Denver. Easy trails lead through scrub oak, prairie and rock formations, with views of the Front Range. A visitor center provides exhibits about the park's geology and wildlife, and the quiet atmosphere makes it a favorite for photographers and walkers. A daily parks pass costs $10 per vehicle. The park is best in the early morning or late afternoon, when the light brings out the color in the rocks.
