The fabled Inside Passage is one of the most scenic sea-lanes in the world, and one of the few where deep-draft vessels can sail close to steep mountain walls. The scenery is unbelievable, with forests in a hundred shades of green, tumbling turquoise glaciers, and evocative towns loaded with history, culture and adventure. With most of Southeast Alaska accessible only by boat or plane, the Inside Passage is a lifeline to the outside world. All day long it hums with activity.
