A compound of two separate but interconnected karstic limestone caves spanning an overall length of nearly 9 Km, the Jeita Grotto is Lebanon’s treasure trove of stalactites and stalagmites. The caves are situated in the Nahr Al Kalb valley within the locality of Jeita, 18 Km north of the Lebanese capital Beirut. The upper cave, which houses the world’s largest stalactite, is open to the public all year round for a nice walk. Its galleries are composed of a series of chambers, the largest of which peaks at a height of 120 m (390 ft). As for the lower cave, it is open only during summers due to a rise in the water level. It can only be visited by boat since it channels an underground river that provides fresh drinking water to more than a million Lebanese. A finalist in the New 7 Wonders of Nature competition, the Jeita Grotto is a Lebanese national symbol.
