Alaska cruises from Los Angeles are a new thing, so there aren't many. Only a few round-trip cruises are available. See the departure calendar below.
Alaska is an extremely popular cruise destination because a ship is the best way to visit the isolated towns and see glaciers. The wildlife and local culture are big attractions. Splurging on a balcony cabin is highly recommended because the Alaska scenery is spectacular.
What is there to do on an Alaskan cruise? Popular shore excursions include dogsled rides, helicopters to glaciers, trains to the Yukon, river floats, panning for gold, fishing expeditions, float-plane rides, seafood feasts, hikes and Jeep safaris. Plan ahead to make the most of each port of call.
