Unhook that leash and let your dog run wild at any of these dog parks -- all free of charge and open to the public.
Stapleton Dog Park: With four acres of sand and grass, dog-sized water fountains and plenty of hydrants, it's an ideal park for any size dog. Canines can roam off-leash in one large fenced-in enclosure. No children or pit bulls allowed.2002 Spruce St.; 303-382-1800
Dog Park at Foothills Community Park: Nestled into the North Boulder foothills, it couldn't be a more gorgeous setting for a dog park. It features two separate fenced-in areas for large and small dogs, but all can be off-leash and do not need to be sight and voice trained. Pit bulls are welcome in Boulder.900 Cherry Ave., Boulder; 303-413-7200
Dog Park at Berkeley Lake Park: Across the street from Lakeside, this is a fenced-in dirt and grassy section of Berkekely Lake Park's west side. Small in size, but a fun patch of land for dogs to play leash-free in the heart of one of Denver's beautiful historic neighborhoods. Pit bull ban enforced.4544 W. 46th Ave.
Dog Park at Cherry Creek State Park: It's arguably the most beautiful dog park in the state with 125 acres of unfenced beauty for dogs to run wild, leash-free. Grass, dirt, trails and a stream -- it's dog heaven on earth. Pit bulls are banned.4201 S. Parker Road., Aurora; 303-690-1166
