Putting it in perspective. I like this aerial taken from north of the tip of Big Island looking back south onto Kohala. It shows clearly the topography of the area and why there is no connection of the road between Pololu Valley in Kohala and Waipio Valley in Hamakaua. All the deep valleys and soaring cliffs in between are clear. You can hike from one to the other in both directions but that's for serious and experienced hikers only.
