Our family of 4 did the 6 hour, 1030a tour to Columbia Glacier. We have teenagers, 15 and 18 and it can be a challenge to keep them engaged on a long tour, the loved the trip as did my wife and I. The wildlife was fantastic, we saw Eagles, Sea Lions, Seals, Puffins and Humpback whales; the captain and crew was very knowledgeable and friendly. We had an excellent visit to Columbia Glacier getting close very close to the face surrounded by ice and mountains. Prince William Sound is just beautiful. Probably the best tour we did on our trip to Alaska.
