This is one of my top 3 rides in the world. The ride circles Haleakala and is 180km with 3200m of climbing and takes in the south side of the island that almost nobody visits, there is nothing really there for a large stretches of it and its also not all paved, so the ride as a whole is 90% great pavement, but 10% is gravel or pavement you wish was gravel:)
