Mystic Hot Springs

Five cast-iron bathtubs set into the travertine are the picture everyone knows, and each fits two adults, which makes Mystic a fine bet for couples. There are also two 20 by 20-foot concrete pools, 2 and 4 feet deep. Every soak is a reserved 2-hour slot, $28.41 for adults, shared with whoever else booked that time, so reserve ahead. The water is cloudy with minerals, and to the relief of many noses, there's no sulfur. You can stay over in a converted bus, a cabin, or at a tent or RV site in Monroe.
