Rosh HaNikra grottoes, Natural sea caves at Mediterranean coast in Northern District, Israel.
Rosh HaNikra is a series of sea caves carved into white chalk cliffs along the Mediterranean coast, with passages that reach far into the rock formation. The spaces show how water erosion has sculpted the soft stone into hollow chambers and interconnected tunnels over time.
In ancient times, the location served as a known landmark and boundary point for those traveling along the coast. During World War II, military forces tunneled through the rock to connect the regional railway network as part of their operations.
The location has long served as a passage point between regions, marking a natural boundary where the land meets open water. Locals and visitors today recognize this as a place where geography shaped how communities lived and moved along the coast.
A cable car transports visitors down to the caves, making access straightforward for most people including those with limited mobility. Visiting when the water is calm gives better views of the rock formations and allows for easier exploration of the passages.
The rock here is soft chalk that waves continuously wear away, meaning the caves change slightly each year as the stone erodes. This allows visitors to witness active erosion happening in real time as waves strike the walls.
