Andrew Anderson Marine Park, operated by the Anderson Island Parks and Recreation District, is a lovely park on the southwest side of Anderson Island in the south Puget Sound (map of area). The nature preserve, sometimes called Andy’s Marine Park, provides the only public saltwater shore access on the island and is part of the Cascadia Marine Trail system. Little-known to boaters, the park is popular with locals and kayakers and makes a great afternoon picnic stop.
The park meets saltwater at a sloping gravel beach packed with sand stars. Behind the beach is a delicate, protected lagoon. An old wooden floating bridge crosses the lagoon, where the sounds of chirping birds fills the air. Once across, a well-maintained trail climbs up into the woods behind. Signs along the way indentify the local where flora and fauna.
We moored at Tolmie Marine State Park and ran the dinghy across. Other moorages are at Oro Bay and Eagle Island Marine State Park. The Anderson Island Historical Society has a detailed map of the island. The terrain around the lagoon bridge can be very muddy—duck feet or rubber boots are helpful.
