The island seamlessly morphs from day to night and as the shops close in Valletta and Sliema, the bars, restaurants and theatres start to hum. Later on, the crowds move on to the many night clubs, most of which are clustered around Paceville. The waterfronts at Valletta and Vittoriosa are popular for their regular night cruises, while roulette, baccarat, blackjack and boule can be played at casinos such as the Dragonara, St Julian’s or the Casino de Venezia in Vittoriosa. There are numerous cinemas showing the latest releases of English and American films, while the theatres offer drama and dance, as well as opera and pop concerts. The Spring carnival in Valletta is a colourful, family affair, while the Nadur carnival is an all-night festa. During the day, there is a water park at Bahar ic-Caghaq open in summer, a bowling alley and a go-karting track at Ta’ Qali. A seaplane offers scenic tours of the island while various companies offer white-knuckle off-road jeep safaris. Professional dive centres offer trips to wrecks and caves, with crystal-clear waters making night dives a unique attraction.
