8. Jackson Hole, Wyoming
Taking a trip to the United States' national parks can be hot. Just ask folks who've stayed in Jackson Hole, Wyoming at the Amangani Hotel. The massive mountains blanketed in smooth layers of white snow provide a sexy backdrop for your time in the steamy pool. You can bring your girl if you'd like, but doesn't this sound like a place for a nice summer time fling? The Old West has a sleek new look and is a lot more interesting when the sexy factor is thrown into the mix.
