The Jeita Grotto is a system of two separate, but interconnected, karstic limestone caves spanning an overall length of nearly 9 kilometers. Located in the Nahr al-Kalb valley within the locality of Jeita, just 18 km north of Beirut in Lebanon, this natural wonder serves as a national symbol and a top tourist attraction. The compound consists of an upper grotto and a lower grotto. The Upper Grotto is known for its impressive stalactites and stalagmites, and is accessible via a walkway. The Lower Grotto is explored with a boat ride, as it's partially flooded, offering a unique subterranean experience. The Jeita Grotto provides a significant source of freshwater to the surrounding areas. Its majestic limestone chambers include the world's largest known stalactite. The site has a cable car for access, a train tour, and a well-organized visitor center, which includes the Jeita Grotto Museum showcasing geological treasures and the history of the caves' exploration.
