Ketchikan is Alaska's southernmost cruise port and often the first stop on an Inside Passage sailing. The town sits on Revillagigedo Island, known for its salmon runs, its totem pole collections, and the surrounding Tongass National Forest. Creek Street, a boardwalk raised on pilings over a salmon stream, runs through the old part of town.
