One of the favourite tourist attractions in Malta, the Blue Grotto is a large, domed cave. Only accessible from the sea, the cave owes its name to the deep azure colour of the water inside. Look just below the water level and you will be able to see bright coral clinging precariously to the inner walls of the Blue Grotto. Unfortunately, significant boat traffic and a blissful ignorance of preservation have led to a visible decrease in the coral at the Blue Grotto over the last 20 years.

The Blue Grotto is accessed via Wied Iz-Zurrieq. Originally a tiny fishing settlement, Wied Iz-Zurrieq has almost entirely given itself over to the tourist trade. The streets here are lined with restaurants, cafes and souvenir shops all vying for the tourist pound. Although the spot is still appealing, you'll find little else to do here beyond admiring the rugged cliffs and the little island of Filfla which lies some 6km out to sea.
