Fairbanks, Alaska

Just outside Fairbanks is Chena Hot Springs, which is the only hot springs pool in Alaska to stay open year-round. And it stays quite busy in the snowy months. It's always memorable -- and many say good for the circulation -- to shock your body temperature by alternating extreme hot to cold, whether you do a snow roll followed by a swim, or just relax in the springs and enjoy the cold air outside. Plus, Chena is quite beautiful in every season, but particularly in the winter when icicles and snow banks surround the spring.
