A Castle Rock Classic This 1.5 mile trail is a great example of the ecology and geography of the Castle Rock area. It offers much of the same experience as the nearby castlewood canyon with out the crowds. This trail is fun and there is beauty to be found here, however, I wouldn't drive more than 30 minutes to visit this trail. The trail climbs to the western rim of the canyon which it follows for the majority of the hike. The trail can be accessed from the "founders village" mitchell creek trail system as described in this guide or from the hidden Mesa open space off highway 86 Mountain bikes and horses are prohibited. Dogs must be leashed.
