"For a relaxing dip, the Chena Hot Springs Resort in Fairbanks, Alaska offers a natural hot spring-fed lake that stays around 106 degrees Fahrenheit year-round. There's a reason this spot ranks among the best hot springs in the U.S. — the outdoor setting, which sometimes offers views of the aurora borealis, makes for an ultra-romantic getaway, though you don't need to stay overnight at the hotel to visit. Once you've gone for a swim, visit the resort's Aurora Ice Museum. Billed as "the world's largest year-round ice environment," it features everything from rooms and sculptures to an ice bar crafted from more than 1,000 tons of ice and snow." - Travel + Leisure Editors
