What started as a small group of clothing stalls in the 1970s has since grown into one of London's biggest (and most crowded) tourist attractions. Centered on the Grand Union Canal, this isn't actually a single market, but a vast honeycomb of them that sell crafts, clothing (vintage, ethnic, Goth, and emerging designer), antiques, and just about everything in between. Here, especially on weekends, the crowds are dense, young, and relentless, with as many as 100,000 visitors on the busiest days. Camden Lock Market specializes in crafts; Camden Stables Market is popular with Goth kids and aspiring rock stars. Print out the (appropriately psychedelic) map of Camden Market from the website before coming; it's helpful for first-time visitors.
