Large off-leash area, limited grass (mostly brush, dirt and some rocky areas). 70 acre+ area, some picnic tables, limited water outlets and restrooms (please bring a water bottle on hot days). Adjacent to Oakland Airport. Lots of ground squirrels and trees. Perfect place for sniffy noses and very safe too! Potty bags available at entrance. Location: Neptune Dr. Directions: Take the Marina exit off of the 880, and go west towards the Marina. Make a right onto Doolittle and a left at Williams. Go to the end and make a right (my doggie brain thinks it is called Neptune Dr.). Follow to the end. The entrance is on the west side. Use a leash for the first 500 feet, them, let ’em roam!
