Boswell Bay State Marine Park is located on the eastern tip of Hinchinbrook Island. Evidence of 1964 Earthquake can be seen here. The former shoreline is now farther inland by more than a mile. This southern edge of the park is a high-energy beach exposed to the Gulf of Alaska. Beach combing and hunting are popular here. Areas of the park are adjacent to the Copper River Delta State Critical Habitat.

Please note that there are no sources of fresh water within the park.
