Looking to tread terrain still untouched by foreign stag expeditions? Want to unwind in luxury or drink up the sun? Lonely Planet lists the world's top 10 party cities in its new guide, the "1000 Ultimate Experiences." This list is not endorsed by Reuters.

1. BELGRADE, SERBIA

The long years of bad press that kept Serbia off the map have now passed, and foreigners are now realizing what locals always knew - that Belgrade really rocks. With an exuberant population and its legacy as an intellectual hangout, Belgrade offers varied nightlife, ranging from eclectic watering holes for those in the know, to the busy restaurants and bars of the Skadarlija district and the summer clubs in barges on the Sava and Danube Rivers.

2. MONTREAL, CANADA

Easygoing Montreal is increasingly popular with foreign travelers, who enjoy the joie de vivre of a place with bilingual ambience, good local beer and even skiing at nearby Mt Royal. Montreal's irrepressible student population and atmospheric old quarter give the city a light-hearted, Bohemian air. There are Old World cafes, cool jazz clubs, packed discos and late bars to choose from, plus a popular comedy festival each July.

3. BUENOS AIRES, ARGENTINA

With its unique mix of European and South American cultures, and a native passion for dance, the Argentine capital provides fertile ground for lively nightlife. There's an emphasis on fashion and a diverse range of entertainment offerings in Buenos Aires' barrios. Relax at a swinging jazz club or dance all night by the waterfront; some clubs and cultural centres offer classes so you can learn to tango or salsa like a local. There's everything from Irish pubs and local folk to house parties.
