Blue Grotto and Ħaġar Qim

The Blue Grotto and Ħaġar Qim lie on Malta's south-west coast, about 15 km from Valletta, and are normally combined in one trip. Bus 74 runs from the Valletta bus terminus toward Żurrieq and the Blue Grotto in about 45-60 minutes, roughly every 30-60 minutes, and the route should be confirmed in the Tallinja app. Fares are about EUR 0.75-2.50, while a taxi costs roughly EUR 25-35. The Blue Grotto is a group of sea caves on the cliffs at Wied iż-Żurrieq, visited by small boats that run from the small harbour below a viewing platform. In calm conditions the water inside the caves glows in shades of blue, and the boat ride lasts around 25 minutes. Trips are cancelled when the sea is rough, so the weather should be checked before travelling. Ħaġar Qim is a prehistoric temple complex on a hilltop nearby, among the oldest free-standing stone structures in the world and part of Malta's UNESCO-listed megalithic temples. It has a visitor centre and a protective canopy, and the neighbouring Mnajdra temples sit a short walk downhill. A suggested one-day arc is to travel in the morning, when the sea is calmest and the light best for the caves, take the boat trip, then continue to Ħaġar Qim and Mnajdra for the afternoon, before returning by bus. Exposed cliff paths and the walk between sites make this the more physically active of Malta's day trips. May to October offers the most reliable sea conditions, but summer is hot and shade is limited at the temples. Food and rest stops are limited to cafes at the Blue Grotto viewpoint and the temple visitor centre, so carrying water is wise. A day costs about EUR 25-45 per person including the boat trip, temple entry and transport.
