Wouldn’t it be great to stand in the middle of the world’s tallest mountain and dip your toes into warm ocean water? Well, you can! And, even better, it’s in Hawaii smack dab on the Big Island. That’s right. Mauna Kea, from its base at the bottom of the Pacific Ocean, rises more than 33,000 feet to its highest peak, yet at the 19,000 foot mark, you can swim, surf, snorkel, paddleboard or whatever you want right at the Mauna Kea and Hapuna Beach resorts. How good is that?
