Beautiful park. Beautiful, somewhat rugged hike down to the river directly from the campground. I couldn't find much information on where I could swim or paddle board from, but ended up finding a trail that led to a beautiful sand point in lake Pepin. There's also a nice swimming beach off of the main road that goes into Old Frontenac. The campsites were closer together than I expected. It wasn't very busy Wednesday through Friday, but it got pretty loud once the weekend guests showed up Friday night.
