The smallest Out of the Valley model is the Forest Sauna, which features two benches on either side of a heater and fits two people lying down or four to six people seated. A large window brings views of the surrounding landscape into the sauna. “The sauna experience is all about connection—to nature, to other people, and to yourself,” says McKelvie. “It’s also good for physical and mental health and people are becoming much more aware of that.”
