Drigon Dog Park

Address: 34666 7th St, Union City, CA 94587

Both the small-dog and large-dog sections at this Union City park include agility obstacle courses, giving dogs more to do than a standard open run. Shaded benches and a concrete walking path keep things comfortable for owners, but the water fountains are frequently out of service, so bringing your own water is strongly recommended. The surface is mostly dirt with little grass, though there's generous room to roam.
