Thats a fun drive! You know, you can actually KEEP GOING past Hana onto a dirt rode on the other side of town. Dirt lasts for about 7-8 miles with stunning views. You come out on the other side of the island. Makes for a very long drive.
Disclaimer: Don't get stuck, rental cars are strictly forbidden (which makes it even more fun)! Might have to ford a couple of creeks along the way, but you can make it.
