First thing to know is that you cannot pay for anything there directly... no cash, no checks, no credit cards, no tap, nothing. You need to use the Yodel app to purchase firewood and, even if there is staff present, you'll need to pay for your site on the MN State Park reservations system. What's nice is that there is no convenience charge when you are on site. This totally threw us as we are used to pulling up and paying with cash or card to a human. And, they have no wifi. So you'll have to use your phone or, like I did, use your phone as a hotspot to use your laptop/tablet.
Once that was all finally taken care of, we got to enjoy our spacious site. It was HOT, but there is a tree in the center of Site 7 that offered shade and lots of bushes and trees around that offer shade. We just had to keep moving to get it. Each site has a firepit and picnic table. Site 6 has a trail going through it on the edge while Site 7 had a trail on the other side but it was several feet from the actual site. I'm not sure it ever gets busy there, but if it did, you may have people around your site if you choose those edge sites.
This place was SO quiet! I know that also has to do with the other campers, so thank you to our fellow campers that weekend who kept it quiet. No road noise at all. There are fields nearby, so if it's plowing season I imagine it would be quite noisy and quite dusty.
At the end of September, along with the heat, there were tons of what we later learned were Asian Lady Beetles, which actually do sting. Surprise! Then when they started slowing down, here came the midges/no-see-ums. So I came away with a lot of stings. Boo! My spouse did not. So I guess they just liked me a lot.
I would totally recommend Kilen Woods SP! It was a total surprise to use as we were looking for a last minute place to camp, so that was wonderful. If you're driving along I90 in Minnesota or I26 in South Dakota and need an easy overnight, check this place out.
