This is something NO ONE should miss. We only planned one whole day, and it was not nearly enough time. We had to skip several beaches and hiking. It took us nearly 7 hours to get to Hana, with making about half of the stops along the way. We had rented a Jeep with permission to take it on the back roads, so we made the whole circle around. We had left at 7am, and didn’t get back until way after dark, about 9pm. I would definitely consider taking TWO days for Hana, if time allows! It’s SO GORGEOUS!!!!!!!!
