A Northern lights vacation Alaska promises awe-inspiring views of the aurora borealis amid snowy wilderness and crisp Arctic air. The best time to visit is between late August and April, when the nights are long and skies are clear. Base yourself in Fairbanks or explore remote lodges for a better chance of catching the lights. Combine your trip with dog sledding, hot springs, or glacier hikes for a truly unforgettable Alaskan escape.
