The Haines-Skagway Fast Ferry transits the Taiya Inlet of Lynn Canal, the longest and deepest fjord of North America. Three major waterfalls are viewable from the vessel: Long Falls, Twin Falls and Sawmill Falls. Depending on the season and the time of day, humpback whales, bald eagles, and seals can be seen from the inner and outer decks of the vessel. A knowledgeable Naturalist/Guide will be narrating and answering questions about the natural history, the geology, and man's influence upon Taiya Inlet.
