Though located in a traditional New England country inn, the décor at the Spa at White Barn Inn delivers a dash of minimalism without compromising on luxury. Guests can request a light-of-the-moon plunge, which is a fizz of marine pebbles infused with mandarin orange and lemon essential oils, or an aroma sea bath. The nearby Kennebunk River provides the materials used in the spa’s signature stone massage, while natural marine algae and Maine sea salts are incorporated into the body wraps.
