Hike - Waipio Valley - Big Island of Hawaii

One our recent trip to the Big Island of Hawaii I hike from the look out down to the valley below. The road is paved but access is limited to 4x4s that are checked at the a guard shack. It has to be about 20 percent grade in some spots. Super steep all the way. The valley is about 5 miles wide at the mouth and there are beautiful tracts of farmland planted just in from the ocean. You can see a trail on the other side of the valley. I would like to hike down and across and then back up the other side. That would be cool but I am with a group that is not interested in that kind of adventure. Maybe another trip. On the way back up I saw a Brighton Ski resort sticker on the back of a sign. I thought that was cool. I should have put my shirt back on before Connie snapped my photo too. About 1,000 feet of vertical.
