Best Campgrounds near Frederic, WI

This campground is really beautiful. It's big with over a hundred sites, some with power. No water at the site. Water nearby at stations. Large campsites, most with thick wooded areas between the sites. Most of the trail heads start at the campground. Walked about a mile to the falls area. This was really beautiful and was only a the head was only a couple hundred yards from my site. Unfortunately, I was only able to stay one night as my cross country trip hit this campground on the Thursday before memorial day and the whole weekend was booked. It was cold and a bit muddy (though packed gound) but with some management I was able to keep the inside of the tent clean

I have long overlooked William O’Brien because I thought you had to drive a long way to get away. I was wrong! We planned this weekend with friends to camp in our matching teardrop trailers. We have never really camped with friends before, so the point was to just go, not to really travel far. We loved the trails. It was easy to takes hikes of varying lengths. There were so many different kinds of birds, and the wildflowers were blooming and ferns were unfurling -so many shades of green! This was the first really nice spring weather, and the Savanna Campground was quite full. Several people seemed to be there in groups, but we had no issues with noise. The pit toilets were cleaned and stocked with TP and sanitizer. The shower house needs some paint, but had been cleaned.

The river side of the park had been closed for months for construction, but had just opened two days before our stay. The Riverside campground appeared quite full, too.

All in all, I would visit again. There were lots of people, but it was easy to take a walk and get some space and some nature.

I stayed two nights in the campground and hiked many of the trails in this Minnesota State Park along the St. Croix River. The draw here is the potholes, but we will get to that.

My site was #24. It was tiny and my neighbors were right on top of me. Even in April the campground was mostly full. Do not pick a site inside the loop (the electrical hookup sites) if you want privacy. A few of the sites along the river have a real nice view and are slightly more secluded. The best site it #25. If there is a next time, I will shoot for that one.

The park is laid out kinda funky, but that is a product of it being on the river. Campground and Park Office are on the south end and the attraction is a 2.7 mile walk towards Taylor’s Falls along the highway to get to some very cool, unique scenery. You can drive it if so inclined. We did.

The draw here is the world’s largest glacial potholes. When the river ran 200’ higher than it does today, tornados of water eroded smooth round, massive holes in the rock. Some are so big that they still to this day have no idea how deep they go. Very cool to take the quick hike through the maze of small trails that show off these crazy formations.

So, the campground is cramped, it has lots of noise from the highway, sites are the smallest I have seen anywhere, but on balance the coolness of the rock formations and great views of the river still make this a park to consider.

Oh, and the Park Ranger Theresa is the best ranger I have ever met. She is part of a multigenerational heritage of MN Sate Park Rangers, and her family has a year-round residence in the park. She is so friendly, thoughtful, inviting and experienced. Extra star on this review just for Theresa!

Well, it snowed … in late March. I stayed in the campground in late March, 2025. This is a big park with a diversity of hiking, equestrian, and canoeing options. Since the park runs along the St. Croix, there are beautiful river-side walks to be had. There are also Oak Savanna trails. Several trails are for horses, but that isn’t my scene. I stayed in the campground for two nights. It was cold, rainy, and that turned into 5” of snow. Like many MN State Park campgrounds, you are close to your neighbors with no real private offerings. I stayed in site 66e. It was a typical site with nothing bad nor special about it. The hike to the former Dam site is the neatest thing about the park. I recommend reading the historical information at the site of the dam. Having been here once, I see no reason to come back.
