Fresh Farm Markets operates a total of 11 markets around the Washington, D.C. area, but the one at Dupont Circle is an absolute must-see. Since 1997, this bazaar has been opened every Sunday throughout the year, although you'll find slightly shorter operating hours from January through March. Amongst the crowd, you'll find over 110 farmers that come from five different states, and the last headcount showed that about 360,000 shoppers enjoy the market every year.
