Fall Fun at Grasshopper Farm is an outdoor autumn festival in Knightdale featuring a corn maze and seasonal activities. What to Know: Admission to the farm grounds is free, though some specific activities may have individual fees. The four-acre corn maze is the main attraction, making this outing best suited for toddlers through elementary-aged children who can handle walking on uneven dirt paths. Ample gravel parking is available on-site. Be sure to bring a stroller with sturdy wheels for younger children and pack sunscreen, as the open fields offer very little shade. This is a highly practical weekend stop because of its relaxed pace and convenient location just off Poole Road. You can easily pair a visit here with a quick trip to nearby Knightdale Station Park to let the kids burn off any remaining energy.
