Directions to Tinsley by Car
Navigate to King Island Marina (11530 W. Eight Mile Rd., Stockton, CA 95219). Download maps before you go, as cell service can be spotty. Depending on traffic, the drive takes 2.5 hours from San Francisco and 1.5 hours from the Peninsula and Marin County. As you approach King Island Marina, you will feel like you are in the middle of nowhere—you are in the right spot.
All cars parked at King Island must display a parking permit, which can be purchased from the Marina Store for $10 a day. If the Marina Store is closed when you arrive, write a note on your dash and settle up before you depart. Do not park in reserved areas as your car could be towed. Parking is allowed on the side of the road and on the hill behind the Marina Office. If you are confused about where to park, look for cars with the StFYC burgee.
The Tinsley Island launch dock is directly across from the Marina Store. The regular launch is complimentary. Contact the launch operator with questions or problems at 209-406-6456.
Directions to Tinsley Island by Sea
Tinsley Island is located on the main shipping channel in the San Joaquin River between Little Connection and Disappointment Sloughs. Coming upriver from the Bay, the last flashing red marker is #12, at which point Tinsley is ahead to your right.
The main entrance to the lagoon is at the southeast end of the island, and the secondary entrance is at the southwest end. Both are marked with Club signage. If you are making this cruise for the first time, we recommend you contact members of the Tinsley Island Committee, or other frequent visitors, for local information on information on False River, Michael’s Cut, and timing of the tides.
