Whilst the upper section of St Michael’s Cave has been known for over 2000 years and used for various purposes such as a hospital during World War II, it was only in 1942 that Lower St Michael’s Cave was discovered - accidentally by the sappers whilst driving a tunnel into the lower reaches to provide a secondary exit. A cavern was discovered, with several chambers, which may have been sealed for 20,000 years.
The cavern is of extraordinary beauty, glimmering with white, grey and red stalactite columns, resembling a cathedral with pulpit, chancel and organ pipes. This extraordinary beautiful cavern is remarkable for three reasons: the size of the main chambers, the profusion and variety of calcite formations, and last but not least - a lake of crystal clear water, nearly forty yards long estimated to hold 45,000 gallons.
Today there are organised tours into Lower St Michael's Cave available to the general public. The tour normally lasts around three hours. However, due to the fact that there is some scrambling and minor climbing with ropes involved, duration times may vary. The cave is totally in its original natural state (although it is fully lit). One of the sites visited during this tour is a beautiful underground lake and fortunately for the visitor, who will no doubt not want to forget this wonderful speleological experience, photography is permitted.
People are advised to wear stout shoes and casual clothing. Group sizes range from a maximum of ten and a minimum of five. Due to the unusual nature of this tour, children under the age of ten years are not allowed. Three days prior notice is also necessary for bookings. For details and costs contact the numbers below.
