Williams Grove Farmers Flea Market

1 Steam Engine Hill,
Mechanicsburg, PA 17055
(717) 766-4001

The Williams Grove Flea Market is hosted by the Williams Grove Historical Steam Engine Association. This market takes place from sunrise to 2 pm each Sunday year-round (weather permitting). The market offers something for everyone with regular vendors offering wares such as organic pet foods, tools and building supplies, handmade jewelry, homemade soy candles, antiques, produce and plants, and collectible cards.  With more than 600 vendor spaces available, no two trips offer the same experience. Parking is free and the ample grounds allow plenty of room to walk off delicious treats like Italian hot sausages, hot dogs, funnel cake, French fries, ice cream and freshly squeezed lemonade. 

Beginning January 1, 2018, dogs will no longer be permitted at the Farmers' Flea Market.

Historic Marker: A marker located on Williams Grove Road, .5 miles South of Williams Grove Park reads: "With its excellent railroad connection, this became the site of the Great Grangers' Interstate Picnic Exhibition, founded 1874 by Robert H. Thomas of the Pennsylvania State Grange. A week's attendance at this annual event was estimated at 100,000 or more by the 1890's. The John Williams House, built around 1799, is nearby."
