This is a small county park and campground off the beaten path. It is located adjacent to the Little American Falls, and alongside the Big Fork River water trail. There are several campsites you can drive into, and if it is not the muddy season you could drive with a trailer or small RV into some of the the camping sites. Although the sites themselves are pretty well kept, campers are advised to pack out their own garbage but it seems some folks don't feel they have to--so there is some litter around, and evidence of campers burning garbage in the firepits. There is little to no cell phone service here, no on site ranger or camp host, but sites have basic picnic tables and fire rings, and there is an outhouse available. You should bring your own water; any RV's should know there are no hookups of any kind, but you are allowed to use a generator here.
The main appeal of this campground is access to the river, which involves going down a steep bank (there are stairs) but worth it for fishing or kayaking or canoeing. The falls are beautiful, and worth a visit. There arent official biking or hiking trails but you could easily walk or bike on the back roads adjacent to the campground. If you want more privacy, there is a canoe campsite on the bank opposite of the county campground, just downstream of the falls, that is maintained by the Minnesota DNR and is water-access only.
There is no cost to camp here, but also no reservations so first come first served. For maps, you can refer to the Koochiching County recreation maps to see location, which are here:
