Blue Hole Malta

About this site

The Blue Hole at Dwejra on Gozo island is a natural cylindrical hole in the limestone shelf, 10 m in diameter and 15 m deep, that opens through an arch at 8 m into the open Mediterranean. The arch drops to 25 m on the seaward side, connecting to the Azure Window collapse site and a dramatic wall leading to 50 m. The resident date mussels, dusky grouper, and dense moray eel population make it an outstanding Mediterranean dive.
