Blue Grotto

The Blue Grotto is a network of sea caves cut into the cliffs near Wied iz-Zurrieq (Wied iż-Żurrieq), a small seaside hamlet on Malta's south coast below Qrendi. The name comes from the colour of the water inside the caves: in sunshine, light bounces off the seabed and throws blue, turquoise and green reflections onto the limestone walls.

Two ways to see it

From the road above, a viewpoint looks down on the great natural arch that frames the main cave, with the islet of Filfla out to sea. Allow time to stop here before heading down to the harbour. To go inside the caves, take one of the small open boats that leave from the harbour at Wied iz-Zurrieq. The trip loops along the cliffs and slips into the caves, close enough to see the colours on the rock.

Boats need calm water to enter the caves, so trips depend on the sea state on the day. Check the current fare at the ticket booth before you board.

Making a half-day of it

• Try a sunny morning and check the sea conditions before travelling.
• Hagar Qim and Mnajdra are a short drive along the same coast road.
• The inlet is also used as an entry point for scuba diving along the reef and caves.

Check parking and toilet availability before travelling to the harbour. Wear shoes with grip and bring a light layer if you go out in spring or autumn, as it can be cool on the water.
