Overview

Castle Flats Cabin is located on Kupreanof Island on the coastal waters of southeastern Alaska. It offers access to a variety of outdoor recreational opportunities, as well as a secluded place to enjoy its beautiful surroundings. The cabin is accessible only by boat or float plane from Petersburg, and tides impact access. During low tides, a 2-mile hike is necessary to reach the cabin. Visitors are responsible for their own travel arrangements and safety, and must bring several of their own amenities.

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).
