Start at Mdina, the ancient walled city, and explore its narrow streets and Baroque architecture. Visit the Cathedral of St. Paul and enjoy stunning views from the Bastion Square. Continue to the capital, Valletta, the European Capital of Culture for 2018. Admire the grand architecture in the city's main squares, such as St. George's Square and the Grandmaster's Palace.
In the morning, take a boat ride from Wied iz-Zurrieq to the Blue Grotto and marvel at the clear blue waters of the sea caves. Afterward, head to Marsaxlokk, a traditional fishing village known for its colorful boats and fresh seafood. Take a stroll along the promenade and explore the local market.
Take a ferry to Gozo Island, known for its stunning cliffs, pristine beaches, and beautiful countryside. Visit the Ggantija Temples, one of the oldest free-standing structures in the world, and enjoy the scenery at Victoria, the capital. In the afternoon, head to Comino Island and relax on its secluded beaches, such as the Blue Lagoon.
In the morning, visit the Three Cities, an area with historical significance that includes Birgu, Senglea, and Cospicua. Explore the fortifications, narrow alleys, and beautiful churches. In the afternoon, head to the Hal Saflieni Hypogeum, an underground temple that dates back to 3600 BC. Book tickets in advance as only 10 visitors are allowed per hour.
