Bay seniors looking for a corner of Sausalito that has not been overrun by battalions of tourists should drive into Marinship, an industrial area best known for housing the Bay Model. Head out closer to the Bay and you’ll find a Marina with kayak rentals, the indoor/outdoor Provencal Le Garage restaurant and, most surprising of all, an actual beach. Schoonmaker is small but sandy, the water calmer and warmer than the rest of the Bay, ideal for younger grandkids. A walk away is Dunphy Park with bocce ball and volleyball courts. Free.
