This popular site attracts over 100,000 visitors per year, with tourists flocking here to see the grotto via local boat trips from Wied iz-Żurrieq. It’s also an extremely popular diving and snorkelling spot, with very clear, deep waters. Blue Grotto is a complex of seven caves found along the southern coast of the island, right across from the little islet of Filfa.
The boat trip will take you into the caves themselves, where you will be able to see the glorious colours of the varying shades of blue. It got its name in the 1950s, when a British soldier visited the area and compared it to Capri’s famous ‘Grotta Azzura’, which means ‘Blue Grotto’, because of its clear, bright blue waters. If you are a fan of natural wonders, then one of the things furthest up on your list should be the Blue Grotto.
