The Costa Mesa Bark Park is a 2-acre fenced in off-leash dog park build for the residents of Costa Mesa and surrounding cities.  Conveniently located next to the 405 freeway and the OC Fairgrounds, this park has a separate small and large dog play area, fresh water, grass, trees, benches, trashcans, and of course, poop bags, free of charge.  After the sun sets, the park is lit by LED lights until it closes at 8:45pm.
