Rio San Gabriel Park

Address: 9612 Ardine St, Downey, CA 90241

Locals show up regularly with their dogs at this Downey park, which has separate fenced runs for large and small breeds across a grassy, open layout. Waste bags, benches, restrooms, and a parking lot are available, though some visitors have noted that maintenance in the wider park can be lacking. The dog area itself stays fairly active and has a sociable atmosphere.
