Well, I made it, albeit only the first peak. The bus driver told us where to go after we got off the bus and the guard at the Hawaiian golf club told us of landmarks to watch out for as people have been getting disorientated on the way down. Some mud on the first part of the climb us which was no biggy, then you climb out into the open and the views are out of this world, I got a bit anxious with the rope ascents at the top, but we made it. It was so worthwhile.
We bought snacks and lots of water for the climb, much needed, and of course do not forget your camera, those pictures are so worth it.
