The area is in a drought which means NO waterfalls. Just got back from Maui and did the drive. If we would have known the drought issue we would not have gone as there was not alot to see that we couldn't see in other parts of the island. The 50 mile drive and 15 mph speed limit on most of it is rediculous. The road is very, and I mean very treacherous as there are alot of one way bridges and you get people driving like maniacs.
