Seal Point Park

Address: 1901 J Hart Clinton Dr, San Mateo, CA 94401

Sitting along the bay in San Mateo, this spacious off-leash park draws a steady crowd of local dogs and their owners. Separate fenced sections for large and small dogs give everyone room to run on open dirt, and paved paths wind through the property with views of the water. Waste stations, water fountains, and restrooms are all on-site, though there's no grass or shade to speak of. Wind off the bay is a consistent factor, so plan accordingly.
