Long ago, before humans populated Earth, the land was home to giant beings called dinosaurs. This was the Jurassic Period and the Tyrannosaurus rex was the undoubted king of the jungle. Eventually, the dinosaurs became extinct and humans discovered the possibilities of DNA science. One guy decided to build Jurassic Park, a theme park around dinosaurs engineered from dinosaur DNA (extracted from mosquitoes preserved in amber) inserted with frog DNA (and the frogs, unfortunately, could change their sex depending on the population structure... allowing the dinosaurs to mate and reproduce), in Isla Nublar (fictional, supposedly in Cuba). Doubling as part of Isla Nublar is this portion of the Ka'a'awa Valley. It's where the dinosaurs were chasing the children and a scientist down a valley.
But aside from Jurassic Park, K'a'a'awa Valley was also where a road scene in 50 First Dates was shot. The girl with amnesia drove on this road daily and so the guy who liked her placed blocks here to make her stop, including a penguin. She also beat up a guy here who was pretending to hurt the guy who liked her.
I haven't seen Godzilla and Lost, but scenes from this movie and this TV series were shot along this valley too.
