The Prince William Sound ferry routes take you through the incredible beauty of the Gulf of Alaska and Lower Cook Inlet. Glaciers and fjords, concentrations of seabirds and marine wildlife may be seen at every turn. The AMHS ferry transits Prince William Sound daily during the summer, linking towns and villages and providing visitors access to a bounty of recreational and sight-seeing opportunities.

Kodiak & the Aleutians

From the gentle coastal grasslands of its islands to the rumbling snow-capped volcanoes along its shores, Southwest Alaska is a region known for its spirit of adventure. Stretching from Kodiak Island to the Aleutian Chain, it is home to the largest brown bears in the world, as well as walrus, seals, dozens of species of seabirds, giant halibut and plentiful salmon runs. It also has many rich cultural and historical treasures.
