A Ride on the White Pass & Yukon Route Railroad: This sightseeing train excursion was created as a result of the Klondike Gold Rush of 1898, though it wasn't completed before the rush ended. The narrow-gauge train follows the path that pioneers in search of Klondike Gold climbed in order to get to Dawson's Creek in nearby Canada. The tracks wind around granite mountains, trundle across steep gorges and pass through two tunnels. Virtually all visiting cruise lines offer the train ride; it's the most popular tour here.

Historic Tour of Skagway: Pick up a map at the Skagway Visitors Center for a self-guided walking tour. The building itself is distinctive because its builder collected more than 8,800 sticks of driftwood -- and then nailed them to the building's front.

If you prefer a drive, fast-talking guides in period garb lead the Skagway Street Car Tour, a two-hour look at the port's Gold Rush history onboard a restored yellow Mac Model B.

Gold-Panning at Liarsville Gold Rush Trail Camp: A stop at this recreation camp, which was set up by press men who were supposed to be reporting from the front lines of the Gold Rush (thus Liarsville), is often packaged with the train tour if you go one way by rail and one way by bus. As part of the setup, today's Liarsville also features a campfire, salmon bake and a ragtag band of entertaining storytellers.

Dog Sledding and Glacier Flightseeing: This combo tour is a budget-buster, but it's a unique way to experience the glaciers. You'll get a turn at mushing the dog team. It's available onboard, as well as through Temsco Helicopters (1-866-683-2900).

Ferry to Haines: If you've been to Skagway many times before, the town of Haines is a quick passenger ferry ride away. Go whale-watching and visit the American Bald Eagle Center downtown -- just factor in 45 minutes each way and ferry schedules that change daily.
