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 terrain is grassy and uneven, so leave the umbrella stroller at home and opt for a sturdy wagon instead. There is plenty of free gravel parking on-site, and portable restrooms are available for visitors. This is an easy, low-pressure outing for a September weekend. You can spend an hour navigating the maze, grab some seasonal photos, and head home before naptime without breaking the bank.
