Walked along the pier to the Mt. Roberts tram, which offers panoramic views of the area. Not cheap ($31pp) but very scenic and very well run by the local Indian tribe. Two excellent films plus gift items are on display at the top and hiking trails are available.
Having taken the White Pass trip previously, we opted for the expensive ($42pp) but interesting old-time trolley tour. Skagway is not over-filled with attractions, but this tour, nicely narrated, makes the best of them.
