Situated on sprawling hilltop acres overlooking the Hudson River, the main tower of Castle Hotel & Spa forms the highest point in Westchester County. Castle Hotel & Spa is a medieval-style structure that was meticulously transformed into a luxury hotel, offering guests royal-quality service, luxurious guestrooms, and the award-winning Equus restaurant which features Auberge-style, natural French-inspired cuisine. The luxurious new THANN™ Sanctuary Spa is an oasis of peace and tranquility where a holistic treatment approach aims to rediscover inner physical and mental wellness. Only 25 miles north of Manhattan, Castle Hotel & Spa opened as a luxury hotel in 1997; 16 years after being designated a historic landmark.
