What a pleasant campground! My family stayed here when on a trip to explore the Devil's Lake area and we'd be thrilled to stay here again in the future.
Camp sites were a little tight, but adequate for a car and large dome tent. Most of the sites were occupied by RVs or tow-behind campers.
For amenities, there's a nice beach along the river, a rustic playground, clean bathrooms with showers, and lots of open grassy areas for recreation too. Plus, Sauk City is within walking distance in case you need any basics or food.
