Andrew’s (or Andy’s) Marine Park is on Anderson Island in south Puget Sound. There are several ways to enjoy this trail system, including the two locations described below, as well as the beach.
Andy's Marine Park
From the trailhead, hikers delve into a thick, mossy forest to emerge onto the beach on the eastern shore of Anderson Island. As you go, helpful signs point out the names of plants growing along the trail. When the trail opens up on Puget Sound, a wooden bridge spans a tidal lagoon in Carlson Cove to deliver you onto the beach.
Jacob's Point Park
This loop trail takes you around a peninsula, with several short spur trails to viewpoints of small bays and marinas, Puget Sound, and Mount Rainier.
Each viewpoint has features picnic tables, and there is beach access as well as a composting toilet available. You can also learn some local history and see a chimney remaining from a long-standing homestead.
There is a Washington Water Trails campsite here that can be reserved through the Anderson Island Parks Department. Stretch your legs along the 0.75 miles of public beach and peer off across Puget Sound before heading back.
