We headed out around 8am on our journey to Hana. 46 one lane bridges and 620 turns......each way. We stopped several times to take pictures or hike to waterfalls. All in all, it made for a long day, and we ended up just wanting to go home. It was pretty, we had an entertaining and informative road to hana CD to listen to, but we were pooped. Maybe if we had done it on the front end of our vacation it would have been better for us, but we were just thinking of going back to our hotel and snorkelling.
But...we can say we did it, and we DID have fun along the way.
