A lovely park north west of Madison. It's an enjoyable 25 min drive through rolling farmland. The scenery at the park is idyllic with the hills and lake and mature trees. The main entrance leads to several hiking trails (dogs are allowed here on-leash). However, if you are looking for the off-leash dog area you need to go about half a mile or so down the road to another entrance. (This is also a fishing access point.)
We visited during the week and we were pretty much the only ones there. This was good, because it meant even the anti-social Lola B.Dog got to strut her stuff. I imagine it may be busier during the weekend, but it's probably more of a place to go to do your own thing versus some of the other parks that are a bit more "social".
One important point: the off-leash area is NOT fenced. Most of it borders woods, farms, or a lake BUT there is probably about a 50yd stretch of trail between the parking lot and where the trail becomes more protected where you are walking within 20yd of the road. If your dog is a wanderer you may either a) not want to come here or b) keep them on a leash at least for this part. Oy, it made me a little nervous.
(Can you tell I'm a worry wart?!) Okay. Now that secret's out.
Anyways, all in all it's a lovely park with grass trails through prairie, there are a few benches along the way, but unfortunately no shade as the park ends at the tree line.
