Mount Roberts Tramway
To see unparalleled views of Juneau and the Gastineau Channel, you must take this aerial tramway if you're in the area. It is one of the most vertical, taking you from the seaport to almost straight up the mountain. There's a gift shop, a place to eat, and a restaurant at the top. While landlubbers may have to pay for tickets, cruise lines might give them out as part of the free excursions.
