About Swan Lake Cabin Petersburg
Overview
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.
Recreation
Favorable rock, ice and glacier climbing conditions are found throughout the area. The Cascade Creek Trail can be reached by boat from the cabin. Beginning at the west end of the lake, it leads to Falls Lake and a three-sided shelter about a mile away. The trail terminates at the Cascade Creek Cabin, 5 miles out, in Thomas Bay.
Fishing and boating are also popular activities. Two rowboats with oars are available at the cabin, however, life jackets are not provided and guests must supply their own. Guests may also wish to bring a small outboard motor. Anglers may find rainbow trout in the lake.
A sand bar for tent camping or picnicking is also available. Wildlife viewing and hunting are also popular pastimes. Hunting is available as per state or federal hunting regulations; click here for more information from the Alaska Department of Fish and Game.
Facilities
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.
