Just 25 miles north of Manhattan, Castle Hotel & Spa offers a haven for tranquility and relaxation on a stunning hilltop setting with astonishing views of the Hudson River Valley. The 8,000 square-foot Sankara Spa features amenities such as steam, whirlpool, relaxation lounges, and a private VIP treatment room. Private health and fitness classes are available by reservation.

The stunning architectural design of the spa gracefully emerges from the serene wooded landscape in a simple yet sophisticated building that utilizes stone walls and minimal exterior openings to blend with its peaceful setting. A massive stone wall guides the guest through an opening into a sheltered interior courtyard. The walls flanking the courtyard are transparent floor-to-ceiling glass creating a contrast with the solid stone wall exterior.
