This place is amazing, ive never heard of it and there were no signs of anyone ever jumping it before. We decided to name it "Wahi Nana Lele" which means Lookout Leap since it is so close to the Lanai Lookout.
From Honolulu head East on H-1. When freeway ends keep going straight on Kalanianeole Rd. through Hawaii Kai and go past Haunama Bay. After passing Haunama Bay drive about another mile until you see a shooting range to the left. Park in the next parking lot on your right (Lanai Lookout). Walk back toward the shooting range and right across the street from the entrance take a trail down to the water. Follow the cliffs to the right and you will see the jump spot, you can't miss it! Just be careful because the waves can be VERY dangerous here, and it should only be jumped on a really calm day.
