There may be limited sunlight in the northern city of Reykjavik, but the locals here really know how to make good use of those long, cold, and dark winter nights. Be blown away by the bright lights of the bars and clubs that line the streets and heat things up on the dance floor.Due to the high cost of alcohol, the nightlife only gets going very late as most Icelanders tend to have a few drinks at home before hitting the town. Travellers arriving in Reykjavik by air should not pass up the opportunity to buy cheap alcohol in the duty free store at the airport.Once sufficiently warmed up for the night, head to trendy Laugavegur where most of Reykjavik's 100 or so bars and clubs are centred, dotted around the strip and its side streets. On busy Friday and Saturday nights, it's not uncommon for the street to be filled with people all night long. On a side note, the drinking age in Iceland is 20.
