Valletta
The capital is one of the smallest in Europe and one of the most concentrated. UNESCO named it a World Heritage Site and European Capital of Culture in 2018. The baroque architecture, cliff-top gardens, and the extraordinary St John's Co-Cathedral — with its Caravaggio paintings and marble floor of Knights' tombstones — make it worth at least two days. See Valletta.
The prehistoric temples
Malta has seven UNESCO-listed prehistoric sites. The Hal Saflieni Hypogeum in Paola is the most remarkable — a three-level underground sanctuary carved into rock around 3600 BC and still largely intact. Book well ahead; daily visitor numbers are capped to protect the site. The open-air temples of Hagar Qim and Mnajdra near Qrendi are easier to visit and have a spectacular clifftop setting.
Mdina
The walled hilltop city that served as Malta's capital until the Knights built Valletta. Only a few hundred people live inside the walls today. Come early in the morning to avoid the day-trippers and to appreciate how genuinely quiet and atmospheric it is. See Mdina.
Gozo
Malta's smaller sister island is quieter, greener, and slower. The Ggantija Temples near Xaghra are older than the Pyramids. The Azure Window sea arch famously collapsed in 2017, but the diving around the island remains exceptional, and the beaches — particularly Ramla Bay with its red sand — are some of the best in the archipelago. See Gozo.
The Grand Harbour
One of the great natural harbours of the Mediterranean. The view from the Upper Barrakka Gardens in Valletta, down across the limestone fortifications and the water to the Three Cities, is unforgettable. Take the ferry across to Vittoriosa (Birgu) for a perspective back across the harbour to Valletta.
The Blue Lagoon, Comino
The small island of Comino has an impossibly turquoise lagoon that gets very busy in summer but earns the hype. Worth a day trip from Malta or Gozo; go early or late in the season to avoid the worst of the crowds. See Comino.
