This state park, in Minnesota Bluff Country, occupies the upper reaches of Beaver Creek, including its primary source Big Spring. The water flows in good volume at about 50 degrees F. A little cold for swimming but some do; just right for trout. Many campers are also trout fishermen.

The campground is along a gravel access road that runs the length of the campground. Most sites are rather small, the electrical sites are about 30 feet wide and are parallel to each other. The first 23 have electricity ($8). The higher sites are tents only, and cart ins.

The campgrounds have water in one building, including showers for campers. But all toilets are vault type.

Hiking is very good. Some trails are rather steep. If you want a more leisurely walk, try the trails that go downstream from the picnic grounds - go over the swinging bridge.

No cell service.
