The tiny isle of Comino, only 3.5 sqr kms, is the perfect hideaway. The Islands' main attraction today is the Blue Lagoon, a sheltered inlet of shimmering aquamarine water. It is a popular day trip for cruises. The Lagoon together with the isle's other bays - St Mary's and St Nicholas' - with their crystal clear waters make Comino the ideal choice for most kinds of water sports, especially diving and snorkelling.
