Xlendi Cave is found in Xlendi Bay. It is best to swim across the bay either on the surface on underwater.  The maximum depth of this dive is 12 metres.  The cave is a bent tunnel leading from one side to another of the rock wall.  At the entrance of the cave floor one can see goatfish, damselfish and cardinalfish.  The cave walls are brightly coloured with starfish, sponges, algae and bristle worms.  Further on in the tunnel there are large boulders and it gets progressively shallower.  Towards the end of the tunnel, the seabed is covered with smooth rocks and shingle. 

Maximum depth - 12 metres
