Cannon Park

Address: 131 Rutledge Ave, Charleston, SC 29401

Shaded benches sit beneath oak trees at this unfenced neighborhood green in Charleston, alongside historic columns salvaged from the old Thomson Auditorium. There's also a small playground on the grounds. No parking lot means you'll likely be walking in, but the open grassy space gives dogs plenty of room to roam. Local owners tend to treat it as a casual off-leash gathering spot.
