Seward Alaska Cruise Ship Tracker – Seward is a port city in southern Alaska, set on an inlet on the Kenai Peninsula. It’s a gateway to Kenai Fjords National Park, where glaciers flow from the Harding Icefield into coastal fjords. Surrounded by peaks, the fjords are a whale and porpoise habitat. The city’s Alaska SeaLife Center has seals and puffins, and fishing boats fill Seward Harbor. To the west, a trail leads to the summit of Mount Marathon.
