We visited Cherry Creek State Park in Denver, CO. There's so much to do in this state park! Cherry Creek Reservoir allows boating, fishing, jet skiing, sailing, water skiing, and swimming. The Cherry Creek Campground has 135 full hook-up sites as well as tent camping. There are showers, laundry facilities as well as a dump station onsite. The 107 acre off-leash dog park has plenty of room for your dogs to play and even has water access.
