In the small Big Hole Valley town of Jackson, this lodge pairs a chemical-free geothermal pool at 100-106 degrees with rooms, a restaurant and a bar, which covers most of what a long valley evening needs. Two rules decide the trip. Children five and under are not allowed in the hot spring, by state law, and the lodge says so in capitals. And the property is closed to the public midweek, with the pool open Monday only from 8 to 10am. Plan for Thursday through Sunday, when it opens by 10am and stays open until 11pm. Adults pay $12, children $9.
