About the Park
Wildwood Park is a nearly 3-acre neighborhood park featuring natural areas and a designated off-leash dog area with a large grassy lawn along a wooded area. Amenities include benches, picnic tables, dog waste bag dispensers, and trash cans. It is unfenced but less crowded than other local options, ideal for quick play sessions.
infoWhat to Know Before You Go
Wildwood Park is an off-leash area without full fencing. Make sure your dog has solid recall before letting them loose, and keep an eye on them near any roads or boundaries.
Best of all, Wildwood Park is completely free to visit — no membership or daily fees required.
