With its cold-weather cruises and wildlife tours, Alaska is a popular vacation destination for a laundry list of reasons. Strangely, its exceptional stargazing often flies under the radar, but its clear, dark skies offer the perfect conditions for drinking in the glittering sky. The top locations include Chugach National Park, Glacier Bay National Park, and Wrangell-St. Elias National Park and Preserve. And since cruises around the coast are so popular, you can gaze from one of the best seats in the house — the water.
