It’s the pursuit of the quintessential country life, perhaps, that brings most people to Cliveden. You can stay there for a week and still not uncover all its corners. During the warmer months, visitors can float down the river in antique boats. The concierge can arrange for lessons at the nearby, exclusive Emsworth Polo Grounds, where professional polo players will suit you up, set you on a horse, and teach you the rules of the game (with a sense of humor, too).
