Don't let the locker-room appearance deter you from the Berkeley Springs State Park's Roman Baths – it's the cheapest spa deal in town. Fill your water bottle with some of the magic stuff at the fountain outside the door – it's mineral-filled and it's free! In the summer, kids will enjoy the spring-fed (but chlorinated) outdoor swimming pool (adult/child under 12 years $5/3) in the middle of the green.
