It is a quite interesting experience to drive to its top from the sea level: at first you are below the cloud cover, then you are driving through the clouds, and in the end you find yourself above them. I do not know of many places on earth that you can experience something as magical as this and I would strongly recommend finding time to get to the top of the volcano if you are ever on Maui.
