Ayia Napa is widely considered the premier nightlife location of Cyprus. Ayia Napa is Greek for "Saint Napa", the patron saint of the town, whose Venetian-era monastery is in the centre of the town, next to the square which today is clubbing central.
It's in the far eastern end of the Cypriot Republic, adjacent to the UK Sovereign Base. Ayia Napa is synonymous with clubbing on the island, having made a transition from a popular, all-ages family holiday destination to a "dance party capital", similar to Ibiza in Spain. In particular, it is popular as the summer holiday destination for followers of London's UK Garage music scene. British tourists are still the most prevalent here, but there are a lot of Russians holidaying in the area. It is also a long-time favourite among Scandinavians.
Beyond the clubbing, however, Ayia Napa attracts tourists world-wide because of its fun-loving (some would say, totally hedonistic) outlook by night and its sandy Mediterranean beaches by day.
