An oceanfront estate held sacred by Hawai’ians adjoins the 370-room Four Seasons Resort Oahu at Ko Olina. The celestial setting makes for an idyllic escape from Oahu’s more touristy scene; here, guests can stroll their own beach and snorkel with sea turtles. Practice sunrise yoga, try stand-up paddleboarding and enjoy preferred tee times at the Ko Olina Golf Club; deep-sea fishing and whale-watching are available at the Ko Olina marina. There are plenty of activities for the kids, along with quiet relaxation by the adults-only pool. Dining ranges from fresh seafood to Italian favorites.
