This will be one of the more unusual activities your family will participate in, and only in Utah. This is a geothermal crater filled with warm mineral water/hot springs, perfect for a warm soak after a day of snow-filled activities. Children of all ages can participate, as long as they have swim diapers, however, this is not your regular swimming pool, so less adventurous children may be intimidated by the cave-like surroundings and the depth of the pool. Scuba diving and yoga are also offered here. Flotation devices are available, too.
