Castlewood Canyon State Park is 2,628 acres and features 100 species of birds, 12 miles of trails, and 60 foot rock-climbing walls. There are two entrances to Castlewood Canyon. The main (east) entrance is off of Highway 83 about five miles south of Franktown. The west entrance is accessed from Castlewood Canyon Road off of Highway 86.

History of the park:

This state park is home to a dam that broke and flooded Denver. Castlewood Dam was built in Castlewood Canyon to try to turn Cherry Creek in a reliable irrigation source. However, the dam broke on August 3, 1933, sending a wall of water filled with building materials, timber, cattle, cars, and debris into Denver. The city remained flooded for several days. Castlewood Canyon officially became a state park in 1964, and later became a Leave No Trace Gold Standard in 2020.

Castlewood Canyon’s main attraction is its trails. The park has a variety of hiking trails that range from 0.5 to 4 miles that provide stunning views of the canyon, with some more difficult trails taking hikers down to Cherry Creek and along the canyon floor.
