The Jeita Grotto is a system of two separate, but interconnected, karstic limestone caves spanning an overall length of nearly 9 kilometers. The caves are situated in the Nahr al-Kalb valley within the locality of Jeita, which is part of the Keserwan District of the Mount Lebanon Governorate. Discovered in 1836 by Reverend William Thomson, the Lower Grotto was accessible only by boat until it was opened for tourists in 1958. The Upper Grotto, however, wasn't fully explored until the late 1950s. Inside, visitors can witness a set of large, awe-inspiring chambers that house various stone formations, stalactites, stalagmites, and columns formed by thousands of years of water and mineral deposits. This natural wonder displays dramatic and intriguing rock formations which are accentuated with artistic lighting, instilling a sense of wonder and enchantment to its visitors. Due its delicate ecosystem, the grottos are well-monitored and conservation measures are in place to protect the site. Tourists can access the Upper Grotto by foot and admire its grandeur through designated pathways, while the journey through the Lower Grotto is typically done by boat.
