This is basically a small amusement park that dresses itself up for the Halloween and Christmas seasons. There is no entry fee and the pumpkins are not terribly overpriced but you'll probably be convinced to spend some money on ride tickets or and maybe a pony ride. It's picturesque enough to get some good fall photos of your little one but since it's in Castro Valley it's warm enough to make them sweat so you'll have to live with that disconnect. I did get to take my son on a super slide for the first time - a little intense for a two year old!
