About

Cascade Creek Cabin sits at the edge of a second-growth spruce-hemlock forest along a gravel beach near the mouth of Cascade Creek in Thomas Bay. This remote hunter-style cabin accommodates up to six people with wooden bunks, a table, benches, and both wood and oil stoves for heat. A pit toilet outhouse is located outside. The cabin provides direct access to the Cascade Creek Trail, which begins nearby and offers varied hiking experiences. The trail is moderate for the first mile before gaining elevation and becoming more challenging. It leads to waterfalls, a whitewater canyon, pristine alpine lakes, and areas frequented by mountain goats. The trail connects to Falls Lake and Swan Lake, both of which have rowboats with oars available. During summer months, cruise ships occasionally anchor in the bay, increasing foot traffic on the trail. The surrounding area is home to deer, moose, mountain goats, and black bears. The forested slopes behind the cabin rise steeply toward Cosmos Peak at 5,000 feet. Activities include fishing, hunting, boating, and wildlife viewing. Access is exclusively by float plane (14 miles) or boat (19 miles) from Petersburg and is tide-dependent. Guests must bring their own drinking water or treat water from the nearby stream, as well as all sleeping gear, cooking equipment, stove oil, and supplies.
