last year we had a very active day in Skagway and it was wonderful. We did the White Pass Cycling Adventure in the morning, which is more coasting down than actually active cycling but very nice. After lunch on board we did the Haines Sea Kajak Adventure. That was great. I enjoyed the cat ride down to Haines on the Lynn Canal. The kajaking in 3- Person boats was awesome because we've seen a lot of bald eagles and seals. It was also funny because there were some waves caused by passing cruiseships. Also the group was very nice. Only the short Haines- highlights- Tour was a little waste of time as there aren't any. I can recommend both.
I think there is also the possibility of combining both train and bike adventure. That sounds good, too.
have fun, CP
