Great shot, Steve. I bet you get a lot of these nice views because you get out and hike the trails, right? Something not everyone gets to see.
Thanks, Jo. Actually the spot where I took that photo is pretty accessible. You take the road north out of Waimea across Kohala, then turn right (east) when you intersect the Hawi Road. Continue on to the end of that road to the Pololu lookout, where there is a great vista. Park there and take the path at the end of the road down to Pololu Beach. The trail takes about 30 minutes going down and about an hour coming back up.

The other end of these sea cliffs is the Waimono Valley - that's the lookout at the end of the spur road off of the highway that connects Waimea and Hilo. That's the same lookout as the notorious 4-WD road that descends into the valley.
From the Waimono Lookout you can see a trail ascending the far wall of the canyon. If you continue on that trail you can eventually wind up at Pololu. I believe there are seven valleys that you cross en route, with Pololu and Waimono being first or last, depending on your direction. I've never hiked it, and at this stage in my life I doubt that I ever will. I understand that the middle parts of that trail are primitive to non-existent. Last year DW and SIL hiked down Waimono from the lookout, crossed the valley and started up the far side. They turned around about halfway up the trail on the far side, partly because of time but they also said the trail was getting pretty bad. But when we were at Pololu when I took this picture, we did encounter some backpackers on the trail who had started at Waimono. They had spent at least one night on the crossing, though.
