Kelingking is one of the main attractions of Nusa Penida, Bali. It has to be on your 3-week Bali travel route, because it looks like a T-Rex head from the top. From the viewpoint, you have a look over the limestone formations, ocean, and Kelingking Beach. The walk down to this beach is a hard one and might even be the most difficult beach to reach in Bali.
