About

Breiland Slough Cabin sits on a small peninsula on the west side of Duncan Canal on Kupreanof Island in the Tongass National Forest. The cabin offers a gravel beach in front and grass flats behind, providing ideal waterfowl viewing opportunities. This hunter-style cabin accommodates up to 7 people with 4 single bunks, and additional space outside allows for tent camping. The cabin includes an oil heater (requiring #1 stove oil), wooden table and benches, counter space, and a covered porch. A pit-type outhouse is located nearby. Visitors must bring their own stove oil, bedding, and cooking utensils. The surrounding area features beach fringe forest and grass flats with scenic views of the Castle Islands to the north. Accessible at any tide from Petersburg via float plane (15 miles) or boat (25 miles), the location provides excellent opportunities for coho salmon fishing, dungeness crab, and shrimp harvesting. The area supports diverse wildlife including grouse, waterfowl, black bears, and marine mammals. The nearby Castle Islands, site of old underwater barite mining operations, offer additional exploration opportunities. Activities include boating, sea kayaking, berry picking, beach walking, fishing, and hunting according to state and federal regulations.
