After hotel pickup in Valletta, head first to the Blue Grotto on the southern coast of Malta.
Several sea caverns make up the Blue Grotto, which is known for a morning phenomenon when sunlight in the grotto reveals the water's many shades of blue. Several caverns have phosphorescent colors from underwater flora; others show a deep blue color. Weather permitting, have time to take a 25-minute boat tour of the caves (own expense).
Continue to Marsaxlokk, popular for its fresh fish and seafood caught by local fishermen. Visit the market to browse the fresh fish along with locally produced honey, wine, fruit jams, vegetable, clothing, and souvenirs. Explore the picturesque village independently before your driver returns you to your hotel in Valletta.
