The Alaska State Parks map of the Resurrection Bay, Prince William Sound and North Gulf Coast state parks shows the unit at the north end of Latouche Island.
Alaska State Parks describes the unit on its Horseshoe Bay page as one of the only anchorages with public uplands in this part of Prince William Sound. The park is undeveloped. Campsites lie along the margin of the large rolling bog north of the bay, and stunted spruce and alder line the bluff above occasional beaches with views of Latouche Passage. The old town of Latouche stood just northeast of the bay, active and historic mining claims surround the park, and all land around it is private. No fee for Horseshoe Bay is listed in the Alaska State Parks fee schedule (as of October 2026).
