The caves are situated in the Nahr al-Kalb valley close to Beirut, about 20 km. You could combine the visit with a visit to the zoo if you’re travelling with kids. The caves have been closed for years due to the war but are fortunately open for tourists again. One part of the tour takes place by boat, en there also is a small trip by mini cable cars at the beginning of the tour to get at the entrance of the caves. There is an upper cave and a lower cave. The lower cave can only be visited by boat since it channels an underground river.
One can find the world’s largest known stalactite in the upper galleries.
