Whilst blasting an alternative entrance to St. Michael’s Cave in 1942, a further series of deeply descending chambers ending in a mini lake were discovered and named Lower St Michael’s Cave. Guided visits to this cave must be arranged independently.

Lower St. Michael’s Cave was discovered in 1942, accidentally, whilst blasting a second entrance at St. Michael’s Cave in order to prepare it for use as an emergency hospital during the Second World War. The cave consists of a series of deeply descending chambers including one containing a small lake.

Lower St. Michael’s Cave Tour
There are organised tours available to the general public. The tour normaUy 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). This cave could be referred to as a show cave as most known formations may be found here. One of the sites visited during this tour is the beautiful underground lake and fortunately for the visitor, photography is permitted. People are advised to wear stout shoes and casual clothing. Group sizes range from a maximum ot ten and a minimum of five. Due to the nature of this tour, children under the age 10 years are not allowed. Three days prior notice is also necessary for booking via the Tourist Office in Gibraltar.
