Berkeley Springs, West Virginia
Berkeley Springs, West Virginia bills itself as the country's "first spa" destination, as travelers have sought relaxation and healing in the area's warm mineral springs since colonial times. Many of the waters are concentrated in Berkeley Springs State Park; its spa features Roman and standard baths, massage services, and more. A la carte prices range from $20 (for a Roman bath) to $80 (bath, shower, and 60-minute massage). For maximum affordability, visit in fall or winter: The nearby Cacapon Resort State Park has a midweek Spa Package including lodging and one spa treatment for $121 per person based on double occupancy, available November through March.
