Rosh HaNikra or Hanikra (Hebrew: ראש הנקרה, lit. "Head of the Grottoes"; Arabic: رأس الناقورة, Ras an-Nakura) is a geologic formation in Israel, located on the coast of the Mediterranean Sea, in the Western Galilee. It is a white chalk cliff face which opens up into spectacular grottos.
The Rosh HaNikra grottoes are cavernous tunnels formed by sea action on the soft chalk rock. The total length is some 200 meters. They branch off in various directions with some interconnecting segments. A tunnel was built during the Second World War for the Haifa-Beirut railroad line, and in 1968 a second one was dug, both connecting the grottoes with each other and allowing access (currently: only exit) along the former route of the WWII railroad. For many years though, the only access to the grottoes was from the sea and experienced swimmers and divers were the only ones capable of visiting. The 400 meters long tunnel dug in 1968 between the grottoes and slightly above sea level improved the situation, and soon after a cable car was built to take visitors down from the top of the cliff to the tunnels. With a 60-degree gradient, this cable car is advertised as the steepest in the world.
