I'm not sure which is more dangerous, the drive up and down the volcano or the Road to Hana. If you blink for too long on either road you're going to end up someplace you really don't want to be!
Yes, that is the ocean you see on the horizon.
This was taken at about 7000 feet up the side of Haleakala as I was going back down the volcano. I have to admit that standing in the middle of this road wasn't one of my brightest moments. Between the cars and the bicycles I had to move back and forth pretty fast. I think the people on the bicycles were more dangerous than the cars!
