Celebrity Summit: 7-Night Alaska Hubbard Glacier

Vancouver cruise port is the main gateway to Alaska, and nearly every Alaska cruise that runs the full Inside Passage route starts or ends here. The terminal is at Canada Place, a distinctive sail-shaped building right on the downtown waterfront.

Icy Strait Point is a privately developed cruise destination adjacent to Hoonah, a Tlingit village of about 800 people on the northern shore of Chichagof Island. Unlike most Alaska ports, this is a purpose-built cruise facility operated by Huna Totem Corporation, the local Tlingit Alaska Native corporation, meaning tourism revenue stays in the indigenous community.

Hubbard Glacier is not a port where passengers go ashore. It is a scenic cruising destination in Yakutat Bay at the northern end of the Gulf of Alaska, where ships slow to a crawl and spend several hours in front of North America's largest tidewater glacier.

Juneau cruise port is the capital of Alaska and one of the main stops on Inside Passage itineraries. The town sits on a thin strip of coast at the foot of Mount Roberts and Mount Juneau, backed by the 1,500-square-mile Juneau Icefield and surrounded by the Tongass National Forest.

Ketchikan cruise port is the first major stop on most Alaska Inside Passage itineraries coming up from Seattle or Vancouver. The town sits on Revillagigedo Island in Alaska's southernmost panhandle, wedged between the ocean and steep forested mountains.
