I wasn’t able to search the web for additional details. Based on the facts you provided and my knowledge of Southeast Alaska marine parks, here’s the description:

Beecher Pass State Marine Park sits along the narrow waterway between Kupreanof and Kuiu Islands near Petersburg, offering boaters and kayakers an intimate encounter with Southeast Alaska’s island-studded coastline. As a state marine park, Beecher Pass is designed primarily for water-based access — there are no roads in, which keeps the experience remote and unhurried.

The park’s sheltered waters make it a natural stopover for vessels traveling the Inside Passage between Petersburg and Kake. Paddlers appreciate the protected channel, where tidal currents bring nutrient-rich water that attracts humpback whales, harbor seals, Steller sea lions, and bald eagles. The surrounding temperate rainforest — dense Sitka spruce and western hemlock — drops steeply to the shoreline, creating dramatic scenery at every turn.

Common activities include sea kayaking, sport fishing for salmon and halibut, wildlife viewing, and beachcombing along rocky intertidal zones. Anchorage is available for recreational boaters seeking an overnight stop in calm waters. Facilities are minimal, so visitors should come prepared with their own supplies and pack out all waste.

The best time to visit is mid-May through September, when longer daylight hours and milder temperatures make water travel most comfortable. June and July bring peak salmon runs, while August offers the best whale watching. Rain is frequent year-round — waterproof layers are essential, not optional.

Beecher Pass rewards those willing to travel by water with solitude, wildlife, and the raw beauty of Alaska’s coastal wilderness.
