Lower St Michael's Cave, St. Michael's Cave Travel Guide

Lower St Michael's Cave, also known as New St. Michael's Cave, is a captivating natural wonder hidden within the Rock of Gibraltar. Unlike the more well-known St Michael's Cave (also referred to as Old St. Michael's Cave), which has been known for over 2000 years, Lower St Michael's Cave was only discovered in 1942 during World War II. Royal Engineers accidentally stumbled upon it while tunneling to create a secondary exit for an emergency hospital in the upper cave.This accidental discovery revealed a breathtaking cavern, potentially sealed off for 20,000 years, adorned with a mesmerizing array of speleological formations. Shimmering stalactites and stalagmite columns in white, grey, and red create a cathedral-like ambiance, complete with formations resembling a pulpit, chancel, and organ pipes. The cave boasts a stunning variety of calcite formations, including rim stone, helictites, coral rocks, flowstone, straws, and curtains.One of the most remarkable features of Lower St Michael's Cave is its 37-meter-long underground lake, estimated to hold 200,000 liters of crystal-clear water. The cave is maintained in its original natural state, with only ropes and lighting added for safety. Guided tours, which should be arranged in advance, take visitors through this subterranean wonderland, involving some scrambling and minor climbing with ropes. Comfortable, non-slip shoes and casual clothing are recommended. Photography is permitted, allowing visitors to capture the unforgettable beauty of this unique environment.
