World's Greatest Flea Markets

Where: Portobello Road

Hours: Saturdays only.

Wake up! The earlier you can drag yourself over to this 1,500-dealer market the better—many shoppers are here at the literal crack of dawn, and most of the serious trading is done by 9 a.m. (This is not to say you won’t have a good time even if you arrive later.) Inside the arcades, specialty dealers offer 300 years of ephemera—the Central Gallery is know for its fine antique jewelry—but don’t neglect the vendors who set up in the middle of the street. They might not have a roof over their heads, but real bargains frequently surface here.

World's Greatest Flea Markets

Where: Spread over 23 different fields/locations in town

2009 Dates: May 12–17; July 14–19; Sept. 8–13; dawn until dusk.

Thrice yearly, the 18th-century hamlet of Brimfield is overwhelmed by a series of antiques shows set up in humongous open fields (and some covered sites) for a six-day stretch. Dealers have flocked here for decades, and virtually anything you collect, no matter how obscure (from taxidermy to taxi dancers’ outfits), will likely show up among the offerings of the 6,000-odd stalls. A word of warning: book your accommodations as far ahead as possible (vendors have been snagging the same hotel rooms for years); bring a flashlight (shows start before dawn); prepare for inclement weather—you’ll be out in the elements a long time; and perhaps most important, write down the location of booths you may want to return to. It’s very easy to get lost. (www.brimfieldshow.com)

Where: Porte de Clignancourt

Hours: Saturdays and Sundays; some dealers open Mondays.

More like a city unto itself than a mere flea market, this vast expanse—really a series of many markets accommodating a whopping 2,500 dealers—could easily take up an entire day. The antique furniture is superb, the chandeliers are splendid, but there are also many, many seductive objects far easier to transport home—everything from enamel kitchen canisters to wonderful vintage postcards of an earlier Paris. In winter, the hot chocolate vendors offer cocoa that is like nothing you’ve ever tasted, plus the landscape is dotted with excellent bistros.

Where: Plaza Dorego, San Telmo

Hours: Sundays only.

On Sundays it seems like the entire population of Buenos Aires flocks to San Telmo, a newly chic boho district. Start at Plaza Dorego then fan out to the various antiques centers, which seem to stretch for miles. Though the market is renowned for its Deco furniture and accessories, there’s also, as at all the best fleas, a multitude of “smalls” to choose from as well. Don’t miss the superb vintage clothes at Gil Antigüedades, 412 Humberto I, where ensembles designed by Eva Peron’s favorite dressmakers are sometimes in stock.

Where: Porte de Vanves, Rive Gauche

Hours: Saturdays and Sundays, before 1 p.m.

Leave the hotel early on weekend mornings and take the metro to the far left bank outpost of Vanves, then walk a few blocks to Avenue Marc Sangnier and Avenue Georges Lafenestre for this small, excellent market, also an open secret among dealers. (Rumor has it that after dealers shop here, they bring their treasures to the far larger Porte de Clignancourt later in the day.) The tables brim with vintage boxes, glassware, old Parisian periodicals, posters, and other souvenir-ready material. Prices are congenial, but remember to bring cash—the ATM machine is a bit of a hike.

Where: Togo Shrine; Meiji Dori; near Harajuku

Hours: First and fourth Sunday of every month.

A lack of Japanese language skills is no barrier to enjoying this terrific market on the grounds of the Togo Shrine—just bring pad and pen, and negotiate the price on paper. Here is the place to find beautiful early-20th-century kimonos and other textiles; winsome antique Japanese dolls; miniature multidrawer cabinets; scrolls emblazoned with stunning calligraphy; and other items you just will not see at the flea markets back home. Bonus: the market is not far from the Harajuku district, so after you shop you can watch the neighborhood’s trendy dolled-up girls strut in all their glory.

Where: Casabarata, on the road to Rabat

Hours: Open every day.

A Parisian friend who has a house in Tangier swears that he finds incredible items at this sprawling market, and that another expat he knows recently found a valuable gold cigarette lighter hidden in the rubble. A maze of broken concrete sidewalks brandishes everything from new mattresses to secondhand sinks, wonderful tin lanterns, all manner of fabrics, and the occasional truly rare treasure. Bring plenty of patience and a trained eye, and be quick—development is threatening to overwhelm this labyrinth.

Where: The Rose Bowl

Hours: Second Sunday of every month.

For nearly 40 years, Angelinos have adored this massive flea. More than 2,500 vendors set up before dawn, and it’s a good idea to come super early (before sunrise), if only to allow enough time to peruse the estimated five miles of booths. Look up occasionally from the tables of mid-century collectibles and the racks of vintage clothes, and you just might see Ashley Olson or Clint Eastwood shopping along with you—both have been known to enjoy treasure hunting here.

Where: Plaça de la Seu, in front of the Catedral de Barcelona, Barri Gòtic

Hours: Thursdays only.

Every Thursday, the Plaça de la Seu at the base of the massive 15th-century cathedral—the most famous edifice in Barcelona (not counting the Gaudís)—hosts an outdoor flea market. The offerings are surprisingly upscale and usually include seductive antique jewelry, lovely old dolls, and printed advertising items. Though the market itself is not enormous and can be covered in one leisurely morning, the quality of the goods makes up for the small number of dealers.

Where: Hell’s Kitchen Flea Market

Hours: Weekends from 9 a.m. to 5 p.m.

Manhattan’s Antiques Garage, adored by legions of New York collectors, was slated for demolition but has been saved from the wrecking ball—at least for the foreseeable future. This bi-level concrete parking lot is a survivor from the days when the neighborhood was full of antiques venues. The 100-plus vendors in the Garage showcase everything from paintings to Puccis, spittoons to old Sears catalogs.

Where: Marché aux Puces de St.-Ouen

Hours: Saturdays to Mondays from 7 a.m. to 7:30 p.m.

More like a city unto itself than a flea market, this vast expanse—really a series of many markets accommodating a whopping 2,500 dealers—could easily take up an entire day. The antique furniture and the chandeliers are splendid, but there are also many, many bewitching objects far easier to transport home, such as early 20th-century French fashion magazines.

• Bring cash Credit cards and fleas don’t usually mix, and an ATM may be far away.
• Check opening hours You don’t want to arrive and find everyone is closing up.
• Pack rain gear and sturdy shoes Just because it’s pouring doesn’t mean markets are canceled.
• Take a pad and pen If you don’t speak the local language, bargain by jotting down numbers.
• Easy in, easy out If trying on vintage clothing, dress in something light that will allow you to slip items over it, as fitting rooms are rare.
• Size matters Sure, you can get that 300-ton temple bell home, but it’s much easier—and more cost effective—to confine your purchases to items smaller than a bread box.
• Don’t exhaust yourself Make sure you have lunch and take time out for a coffee break.
• Be systematic Write down booth numbers if you’re planning on returning to check on a particular find. You don’t want to spend the rest of your trip pining after the one that got away.
