Discover beautifully clear, blue water inside these caves at Malta's cliff coast - the Blue Grotto certainly lives up to its name. The water gets its blue colour from a certain kind of cyanobacteria. The grotto is located at the main island Malta's south, near Żurrieq. As it is situated right by the steep cliffs, access is only possible on boat and in good weather conditions.
You start your trip at Żurrieq, from where boats leave towards the caves. After going along the coast for a bit, you reach the grotto's entry: a natural rock arch of about 50 metres (164 feet) height. The first cave is the actual Blue Grotto, the largest of a number of different caves. Sailing further into the complex, you will not only see deep blue, but also shimmering green, orange and purple water reflecting the light. Bathing is allowed in certain areas. However, you probably won't be in dire need of a cooling swim: even in summer, the inside of the caves is rather cool. Diving trips are also on offer.
Before or after your boat trip, don't miss out on seeing the observation terrace. A 10-minute walk from Żurrieq takes you to the platform, where a stunning view of the Blue Grotto and its characteristic rock arch awaits you.
