The dark sandy, shallow sloping beaches and forest has been a popular recreation area since the 1930's, and historically used by the Tlingits for fishing and hunting. There is a 1/2 mile wood chip trail traversing the southern-most Blank Islands.
The park offers exploring, kayaking, scuba diving, fishing, hiking, and camping. Access is currently by boat or aircraft.
This park encompasses the Blank Islands and a portion of Gravina Island, at the mouth of the Blank Inlet on the East side of Gravina Island (about 4.6 miles directly south of Ketchikan).
