1. Chatfield Reservoir State Park harbors one of the Denver's largest off-leash dog parks. Located at the North end of the park, it offers two large ponds that are fed directly by the reservoir for your dogs to swim in and for you to hike around. Laced around the ponds are literally miles of both manicured trails and rough brush in which your dog can run and you can hike. A daily park use fee of $8.00 is required for admittance into the park, along with a $2 daily dog park use pass. Annual passes are available that cut the costs quite a bit if you are planning multiple visits.
Directions - From Denver, take Wadsworth Blvd. (Colorado Highway 121) south past C-470, and turn left into the Park at the Deer Creek entrance. As an alternate route, take Santa Fe Blvd. south to Titan Parkway, turn west on Titan Parkway to Roxborough Park Road, and turn north to the Plum Creek entrance.
