Home to the most dangerous and exhilarating surf in Hawaii, Waimea Bay Beach Park is known to long- and short-boarders worldwide. In the summer months, the water is calm, making it ideal for swimming. But come winter, it can turn treacherous, with deadly riptides and waves reaching 40 feet high. Follow the lead of the locals and stay out of the water if there’s any question of safety. Not a place for the novice ripper. But if you’re more experienced, you could have the ride of a lifetime.
