Hi there Isac, I believe I have that same photo from my trip to Oahu in March 2010, although my photo isn't anywhere near as beautiful as yours. I just came accross your post as I was seaching for something else, so I'm not even a member of this site. If you'd like to see my photo (I have a video of this scene as well) you can email me at artgal mindspring dotcom and I'll gladly send them to you. I can't recall the name of the place either but I do have the info packed away somewhere. If I hear back from you and you still want to know I'll see if I can find it. This waterfall scene was part of the Lost series that ran on TV for 6 years. I was a huge fan.
