Wills Family Orchard is a bit of a drive, but my #1 recommendation when people ask about a low-key pumpkin patch or a good one for young toddlers. It has a relaxed vibe, inexpensive fun, and a nice balance of things to do without the crowds.
TimberPine PumpkinFest is a weekend pumpkin festival held at the TimberPine nursery; they have a few activities including a bounce house in addition to the pumpkin patch. Pay one admission price for entrance.
Edge of the Woods Raspberry Farm has blueberries, raspberries, & blackberries in addition to a small country store.
