The 7 hour narrated boat trip to the Columbia Glacier was a spectacular experience. The crew on the boat was gracious, attentive and helpful. If you get to Valdez, take this cruise. Sea mammals, sea birds, bald eagles, sapphire colored icebergs, the awesome glacier face up close to view calving, history, science, environmental exploration... great opportunities for photo taking throughout the entire trip. Reservations are handled easily and staff is responsive to questions. The boat is big enough to feel safe and comfortable, but small enough to deftly maneuver through the ice field. Overall a wonderful experience whether you are alone or with friends or family. We met some delightful passengers from all over the world and the feeling on the boat was friendly and relaxed. This glacier is rapidly retreating. You should go now!
