Lower St Michael's Cave Travel Guide

Lower St Michael's Cave, also known as New St. Michael's Cave, is a hidden gem within the Rock of Gibraltar, offering a mesmerizing journey into the depths of the earth. Unlike the well-known St Michael's Cave, the Lower Cave remained sealed for an estimated 20,000 years until its accidental discovery in 1942 by Royal Engineers during World War II. They were creating a secondary exit for an emergency hospital when they broke through into this untouched world.Inside, you'll find a breathtaking display of nature's artistry. The caverns are adorned with a profusion of white, grey, and red stalactites and stalagmites, resembling a cathedral with its own pulpit, chancel, and organ pipes. These formations include almost all known types of speleothems: stalactites, stalagmites, rim stone, helictites, columns, coral rocks, flowstone, straws, and curtains.The cave's main chambers are remarkably large, and the variety of calcite formations is astounding. Perhaps the most impressive feature is the 37-meter-long underground lake, estimated to hold 200,000 liters of crystal-clear water. The cave has been preserved in its original natural state, with only minimal additions of ropes and lights to aid visitors.Visiting Lower St Michael's Cave is an adventurous experience. Tours typically last around three hours and involve some scrambling and minor climbing with ropes. It's recommended to wear sturdy shoes and casual clothing. Photography is permitted, allowing you to capture the unforgettable beauty of this subterranean world. Access is by arrangement only, with tours for a minimum of five and a maximum of twelve people. Children under ten years old are not permitted.
