I highly recommend the White Pass & Yukon train ride from Skagway. If your taking your cruise in the early part of the cruise schedules like May, you will have fantastic snow capped mountains and the views are spectacular. As stated here... up on one side.. down on the other. We did the up/down and the train leaves just minutes away from your ship. The train ride was a highlight of the cruise. If your a photographer, the outside platform is a must. Just make sure you have a warm jacket if your stepping outside.

We also recommend the Island Wings float plane for a spectacular flight to Misty Fjords. This flight originates from Ketchikan.
