Did you know that your dog can run free right across from some of the most expensive homes on the Peninsula? Mornings and evenings, this park on East Battery becomes an off-leash area, meaning you can let Fido chase squirrels to his heart's content. Since there are roads on either side of the park, only pups who reliably come when called should be set free here. But if they can be trusted, there's hardly a prettier spot around to enjoy some quality free time with your furry companion.
