Malibu-born luxury wellness retreat The Ranch opens its Hudson Valley location next month. New York designer Steven Gambrel reimagined the 200-acre, 40,000-square-foot estate that J.P. Morgan commissioned for his daughter at the turn of the century. Guests can take fitness classes like yoga in the former ballroom, swim and work out in the solarium, hike forested grounds and dine on plant-based cuisine. 150 Sister Servants Lane, Sloatsburg, N.Y., 10974.
