George's Bottom Cave

George's Bottom Cave is a cave in the British Overseas Territory of Gibraltar. This together with Tina's Fissure and Levant Cave are a close group of three caves at the southern end of the Upper Rock Nature Reserve.

The existence of George's Bottom Cave was suspected on 27 November 1965 when the Gibraltar Cave Research Group found a small hole in the Rock of Gibraltar near Spur Battery, 310 m above sea level. As the group could feel a draught from this hole they suspected it was the entrance to a cave and they arranged to have a large boulder moved to reveal a larger but still small entrance. The cave was named after George Palao of the Gibraltar Museum. Having entered the cave, visitors find that the passage is tight, which necessitates crawling at some points. Crawling in is made no easier by the cave coral which together with the curtains, columns, straws, and helictites create a variety of limestone formations. However, the cave has six different levels which contain a wide variety of formations in numerous chambers and fissures.
