The largest flea markets in the US number about thirty. Sometimes called Extravaganzas, these unique events bring together more than a thousand vendors and several tens of thousands of participants for each edition. The rarest flea markets held once or twice a year can attract up to 5,000 vendors and 1,000,000 visitors! Although some of the largest flea markets are held weekly, such as the Rogers Flea Market, Renninger’s Mount Dora, Shipshewana Auction & Flea Market, or the Mile High Flea Market, most of the largest flea markets in the US are held monthly. This is the case for the Rose Bowl Flea Market and the Springfield Antique Show & Flea Market. Or the Brimfield Antique Show and Texas Antique Weekend which are held once or twice a year. If braving the crowds and walking for hours in search of a treasure doesn’t scare you, this selection of the biggest flea markets in the US is for you.
