Fall Fun at Grasshopper Farm is an outdoor autumn festival in Knightdale featuring a four-acre corn maze and seasonal activities. What to know before you go: Admission to the farm grounds is free, though some specific activities may have individual fees. The flat, dirt terrain is stroller-friendly, but sturdy closed-toe shoes are highly recommended for navigating the large corn maze. Parking is available on-site in a gravel lot, and portable restrooms are located near the entrance. This is a great weekend destination because it offers a relaxed, uncrowded farm environment where kids can burn off energy outdoors without a hefty admission price.
