Each year, farms throughout Lehigh County open their gates to the public to help educate the community on exactly what they do. Come discover the wide array of farms that are growing fruits and vegetables, making cheese and yogurt, training horses, raising alpacas and so much more.

The event runs noon-5 p.m. Oct. 19 and 20.
