About this park

The cabin is located on southeastern Kupreanof Island, on the edge of the Castle River tide flat in Duncan Canal. The surrounding terrain is predominantly flat, old-growth forest and muskeg. A variety of wildlife makes its home in the area, including moose, deer, black bears, waterfowl and grouse. During spring migration, the flats are host to many bird species.

Recreation
The Castle River Trail is an easy, 1-mile trail that leads first to the Castle River Cabin and continues upstream another half-mile through forest and muskeg. Wildlife can be seen along the trail. Waterfowl, grouse, moose, deer and bear hunting is available in designated seasons as per state or federal hunting regulations; click here for more information from the Alaska Department of Fish and Game. Visitors also enjoy fishing for steelhead from April to May, trout from May to October, and coho salmon in mid-August through mid-September. A small rowboat and oars are provided at the cabin. Life jackets are not provided and visitors must bring their own. Visitors may also choose to bring a small, outboard motor. Crossing the tide flats by boat requires at least a 13-foot tide (local tide tables).
