Jeita Grotto is a famous cave system in which country?

Jeita Grotto is a famous cave system in Lebanon. It lies in the Nahr al-Kalb valley near Jeita, about 18 kilometers north of Beirut, and consists of interconnected upper and lower limestone galleries.

The caves formed through karst processes, as rainwater and groundwater gradually dissolved fissured limestone. The lower gallery contains an underground river, while the upper gallery is known for dramatic stalactites, stalagmites, columns, curtains, and other mineral formations. The system extends for nearly 9 kilometers.

The lower cave was rediscovered in 1836 by Reverend William Thomson. Lebanese explorers later mapped more of the system, and the upper galleries were found in 1958. Visitors traditionally tour the lower level by electric boat and the upper level along walkways, although access can vary with water levels and conservation rules.

A common mix-up is treating Jeita as a single dry cavern: it is a two-level cave system with a significant subterranean waterway. Its underground river is also an important source of drinking water for Lebanon.
