I took my three year old daughter to Berry Patch Farms this past fall. We were there with a group, but I can't say I would go back. The price of the tour as part of the group included a hay ride out to there "fields," a small pumpkin (and by small, I mean a small gourd - not even a pumpkin) and a dixie cup of cider.
The hayride was enjoyable. Kids thought it was great. Then they dropped us in a field to "pick a pumpkin." The pumpkins were definitely not grown here, but dumped in a field. Then we got a hayride back to the main area.
There is a small area with a few animals and a playset for the kids to enjoy. At three years old, my daughter was almost too old for this experience. There just wan't enough for her and she definitely wasn't impressed with the tiny pumpkin (neither was I for that matter).
I think if you have kids three and under, it would be a fun outing. But, skip it for the older ones.
It is free to get into Berry Patch Farms but the pumpkins are expensive! I can tell that the pumpkins are not grown there either, they are definitely bought and then placed in the fields, lol. However it's fun to buy a hotdog and take a free hayride out into the field for pictures. The stand there sells homemade jam and cider and it is very tasty. I can't get over how much the pumpkins cost but I guess you pay for the atmosphere. It can get busy in the fall during the weekend. I've only been in the fall for the pumpkin patch. There are also farm animals and a little playground that makes it worth the drive.
