Stroll quaint villages and boutiques where you’re sure to find the top designer names; dine in the trendiest restaurants; or take in a theater show. Explore history at the Sag Harbor Whaling Museum, or fine art at local galleries and museums. And keep your eyes open; you might just spot a celebrity in casual-mode as Hollywood and New York’s celebrities are often spotted in Southampton, Bridgehampton, East Hampton and other area villages.
