Map of Alaska

Alaska, America's "Last Frontier," is home to craggy glaciers, raging rivers, snow-capped mountains and miles upon miles of wild, windblown tundra. The state shares a border and much of its topographical characteristics with western Canada -- specifically, the snowy provinces of British Columbia and the Yukon.

Inside Passage cruises sail along the state's southeastern coast, from the cannery town of Ketchikan to Glacier Bay National Park. Alaska cruise tours, meanwhile, skim the coastline as well as explore the state's vast interior. Common targets for these vacations are Denali National Park, about 150 miles north of Anchorage, and Fairbanks, a former Gold Rush town some 200 miles northeast of Denali. Some cruise tours even cross the border into Canada, making stops as far east as Calgary, Jasper and Lake Louise, all popular points in the province of Alberta.
