Hawaii is one of the most popular island destinations in the world for a reason. It is the only US state that produces coffee. The only state with a royal palace. And the only place you can swim with dolphins, climb the world's largest volcano, and relax with a fresh bowl of poké and ice-cold mai tai…all in one day. So if you want to say "oooh" and "ahhh" and "wow, double rainbow!" at an unprecedented pace, permanently breathing mango-scented air, and meeting the most relaxed people, Hawaii is the place for you.
