White Pass & Yukon Route Railway — Summit Excursion
Board a vintage 1898 narrow-gauge train at the dock and climb ~3,000 feet in 20 miles on the original Klondike gold-rush route, hugging cliff edges above Dead Horse Gulch past Bridal Veil Falls, Inspiration Point and steel cantilever trestles. It's a National Historic Civil Engineering Landmark and the one thing a first-timer with a single port day would most regret missing. ~2.5–2.75 hrs round trip, departs steps from the ship.
