The Cayman Islands are home to one of the best beaches in the world, so you know this is a great destination if you want to spend your honeymoon with your toes in the sand. What you might not realize is how much else this three-island nation in the western Caribbean has to offer, especially for couples who love nature. Grand Cayman is the largest and by far most visited of the Caymans, due in no small part to Seven Mile Beach, a seemingly endless strand of white coral sand that’s home to most of the island’s best resorts and restaurants. Among these is the Ritz-Carlton Grand Cayman, which boasts the acclaimed La Prairie spa, Eric Ripert’s elegant Blue seafood restaurant, and romantic and indulgent rooms crowned by the 8,000-square-foot Grand Cayman Penthouse — the largest suite in the Caribbean.
