Everyone knows the "Road to Hana." However, few have chosen (or are dumb enough to try) the OTHER road to Hana. The Piilani Highway is the alternate route to Hana for only the most adventurous Maui explorers. Disclaimer: Please to do not take this video as an endorsement of this rather treacherous route. Blind corners, narrow roads and rock slides can make this a very dangerous road, even on the driest of days.
