Swan Lake Cabin Petersburg

Tongass National Forest

Swan Lake Cabin is located on mainland Alaska along the southeast shore of Swan Lake. It is available for reservation year-round and provides access to a variety of recreational activities, including hiking, fishing, hunting and viewing wildlife. The cabin also provides spectacular scenic views of the surrounding area.

The cabin can be accessed only by float plane or helicopter. The adjacent lake is normally frozen from November through early June, further limiting access. Guests are responsible for their own travel arrangements and safety and must bring several of their own amenities.

The A-frame cabin was rebuilt in 2005-06 and has two wooden bunks and a sleeping loft to accommodate up to seven people. It is equipped with a table and benches and a clean-burning oil heater. An outhouse with pit toilets is provided.

Water for drinking, cooking and cleaning purposes is not provided at the cabin. Water taken from the lake and the nearby stream should be treated or boiled before consumption. Guests are encouraged to bring their own drinking water if possible.

Guests will need to bring their own sleeping bags and pads, cook stove and cooking gear, towels, food and clothing, fire starter and garbage bags, among other necessities. Guests are advised to bring enough kerosene or No. 1 heating oil for the oil heater. It burns at a rate of approximately one gallon per day. Oil is not supplied at the cabin.
