Grotta del Bue Marino, Limestone cave in Cala Gonone, Italy.
The Grotta del Bue Marino extends over ten kilometers through the Sardinian coast, featuring numerous chambers with limestone formations and underground lakes.
Archaeological discoveries within the cave chambers indicate early human presence, with prehistoric wall paintings suggesting ritualistic activities during ancient times.
The cave's name derives from the Mediterranean monk seals, known locally as sea oxen, which previously inhabited the surrounding coastal waters.
Visitors can reach the cave exclusively by boat from Cala Gonone, Santa Maria Navarrese, or Arbatax, with guided tours covering one kilometer of the cavern.
The cave system contains a subterranean beach where fresh water streams converge with salt water, creating distinct geological patterns in the rock formations.
