That is the only word that can describe my ride around the NW side of Maui. Lots of climbing, lots of wind, but by far the most amazingly senic road ride I have ever done. I found some pics of the road I was on (I didn't carry my camera) ...it was like this with 1-1.5 lanes for nearly 30 of the 75 miles. With a rainforest to my left and sea cliffs to the right, it was hard not to be distracted. You can see below that some of the grades were fierce!
....more proof that Maui is a a destination where you can really explore on 2 wheels.
