Grindall Island Marine Park is a remote area only accessible by boat or plane. The park includes a public use cabin, a mooring buoy, and a variety of recreational opportunities. The Grindall Island area is known for its salmon and halibut fishing. There is a Sea Lion haul out just east of Grindall Island at Approach Rock.The island and cabin site was homesteaded and operated as a fox farm between 1922 and 1950's. An unmaintained trail traverses the forest from the cabin site to a lake in the middle of the island.
