For years, the Castle Hill Inn and Newport’s green-minded beauty source, Farmaesthetics, heard pleas from guests and customers about starting a spa. A collaboration between the parties was hatched, and the result is nothing short of magical. Discreetly tucked behind a stained-glass door at the Inn, the Retreat, a suite of sunny and peaceful rooms, enlists Farmaesthetics’ natural skincare products, which are handmade with herbs often grown locally. Treatments vary from facials to a couples’ massage to a mineral saltwater soak in an oversized, freestanding tub. Guests step out of the spa renewed and refreshed with a natural energy.
