Park Overview

What is Chatfield State Park?

Chatfield State Park is a 5,381-acre Colorado state park in Littleton, on Denver's southwest edge, built around Chatfield Reservoir where the South Platte River leaves the foothills. You can boat, water ski, paddleboard and fish on the reservoir, swim at a summer beach, camp at one of 197 sites with hookups, ride or hike more than 26 miles of trails, let your dog run in a 69-acre fenced off-leash area, and watch hot air balloons launch. The park is open 5 a.m. to 10 p.m. daily, and a daily vehicle pass is $10–$12 with Colorado plates.

The reservoir exists because of a flood. After the South Platte and Plum Creek overflowed in June 1965, the U.S. Army Corps of Engineers dammed the river; the dam was finished in 1975, the year the state park opened. Today Colorado Parks and Wildlife manages the water and the prairie around it (history and wildlife).

One tip before you leave home: don't type the park's name into your map app. CPW says it gives wrong directions. Use 9700 S Wadsworth Blvd or 11500 N Roxborough Park Rd, Littleton, instead (entrances and directions).
