"One of the best places to feel the local side of Reykjavik life, the Kolaportid Flea Market is set in a spacious industrial warehouse close to the city’s old harbor. Open at weekends only, you can find anything from wool jumpers and vintage fashion garments to fermented fish and licorice, plus plenty of second-hand books and decorative knickknacks. Best to go early to avoid the crowds (it opens at 11 a.m.)—and best to have cash on you since many of the market’s vendors don't accept credit cards."
