Blue Grotto

Blue Grotto is a group of sea caves on Malta’s southern coast, near the harbour at Wied iż-Żurrieq. Limestone cliffs form a high natural arch above clear water that shifts through blue and turquoise tones as sunlight enters the caves. A short boat ride takes you inside when conditions allow; from the viewpoint above, you can see the arch and coastline without boarding. Morning visits often bring brighter colours and fewer crowds. Boat trips depend on the weather, so check locally before planning your visit around one.

The caves and the coastline

Blue Grotto is a group of sea caves on Malta’s southern coast, near Wied iż-Żurrieq. The limestone shoreline includes six caves and a large arch. Sunlight entering the water brings out blue and turquoise shades, with the colour changing according to the light.

From the viewpoint above the coast, you can look down towards the arch and sea. A separate viewpoint along the route to Wied iż-Żurrieq has been noted as being at risk of collapse, with part of the area closed. Use an accessible viewing area rather than entering a closed section.

Seeing Blue Grotto by boat

Small boats take visitors into the caves when weather and sea conditions allow. The ride gives you a view of the rock formations and water from inside the cave system. One reported trip lasted around 20 to 30 minutes, but boat service can be suspended, including in spring. Check locally on the day if the boat ride is central to your plans.

Morning is a useful time to visit: the coast can be less crowded, and sunlight brings out the colour of the water. The viewpoint remains an option when boats are not operating.
