The trails are pretty easy, although there are a few small hills. We felt that we got in a moderate 4 mile workout. The best part of the hiking at Castle Rock is the quietness -there wasn’t anyone else around during our hike.

Other activities at Castle Rock include: picnicking, kayaking, cross country skiing, and boating.
