One of my favorite fall activities is picking apples. Door Creek just outside of Madison, making it a quick and easy trip there on a weekend. I would advise going early (right when they open) to avoid crowds, especially around peak apple season (Sept). Prices are very reasonable ($1.35/lb for pick-your-own apples) and be advised that if you don't bring your own bag(s), plastic bags are $0.25 a piece. They had 5-6 varieties of apples when we went last weekend, and the trees you can pick from have ribbons on them. They also had pick-your-own grapes, which is something we did not take advantage of. In addition to pick-your-own, they have many varieties of already picked heirloom apples in their store ($2.50-$3/lb) as well as fresh cider. Their new website looks really nice, and has pretty much all the information you need. Highly recommend!
