Del Mar Dog Park (Off-leash, open dawn-dusk)

Address: 9867 Del Mar Dr, San Ramon, CA 94583

Tucked under power lines in San Ramon, this fenced off-leash spot is open from dawn to dusk and divides into separate areas for large and small dogs. Tanbark covers the ground, water fountains are available, and plenty of seating makes it comfortable for owners to settle in while their dogs play. Summer heat and winter flooding near the creek are worth factoring into your visit, and the larger dog section can get busy.
