I wasn’t able to search the web for additional details. Based on the facts you provided and general knowledge of Prince William Sound, here’s the description:

Boswell Bay Beaches State Marine Park

Tucked along the wild shores of Prince William Sound near Cordova, Boswell Bay Beaches State Marine Park offers one of Alaska’s most remote and pristine coastal experiences. This marine park protects a stretch of rugged shoreline where temperate rainforest meets the cold, nutrient-rich waters of the Gulf of Alaska — a convergence that makes for extraordinary wildlife viewing.

The park’s beaches are accessible primarily by boat or floatplane, adding to the sense of true wilderness arrival. Once ashore, visitors find themselves on uncrowded gravel and sand beaches framed by dense Sitka spruce forest and backed by the snow-draped Chugach Mountains. Sea otters, harbor seals, and Steller sea lions frequent the surrounding waters, while bald eagles patrol overhead and black bears forage along the tide line.

Popular activities include beachcombing, kayaking the protected bay waters, fishing for salmon and halibut, and wildlife photography. The tidal pools along the rocky stretches reward patient observers with starfish, anemones, and small crabs. For paddlers, the bay provides a relatively sheltered launch point for exploring the greater Prince William Sound coastline.

Visitors should come prepared for full self-sufficiency — there are no developed facilities, and weather in Prince William Sound shifts quickly. The best window for visiting runs from mid-June through August, when daylight is long and temperatures are mildest, though rain gear remains essential year-round. This is a park for those who want Alaska at its most untamed and unhurried.
