This is one of the most popular State Parks in Wisconsin because it's on Lake Geneva. In fact, it's the only state park within town's limits. This area has always been a summer getaway, so reservations are hard to get. We went in October, so it was much easier, but the weather was unpredictable.
 The lake is famous for it's mansions, summer homes and the trail which goes around the entire perimeter and is open to the public, no matter how many property lines it crosses.
 The park is on the lake, 2 miles south of downtown. So, a 40 min walk, 11 by bike, though there are hills on both routes. The park has a long strip of beach that almost seems like a shoulder to the main road. There's a fishing lagoon with a bait vending machine. The campsites and trails are further back, and out of the wind.
 The sites are generally spacious, some are oddly shaped. The further back you go on the main loop though, actually brings you closer to town. You can hear events taking place at the High School even though it looks like you're in the woods.
 The main restroom and shower facility is brand new and spotless.
Too many things to see and do in the area to list here but I'd point out the Boat House Bar & Grill is right next to the entrance. It has a big patio and is dog friendly. Easy walking distance from the campground. Good food at a good price.
 Outside of town, Lake Geneva County Meats is a butcher shop and more with a terrific selection and variety of brats (among other things) and can supply all your cookout needs.  Also, check out Royal Oaks farm & Orchard. In season, they have the greatest variety of apples we've ever seen. Better still, they are well labeled telling which types are best for what use. Of course, donuts and cider too.
