If you're looking for a beginner backpack spot, with privacy and not too far from the cities, then this will fit your bill. You can either do a short-hike from the parking lot via the road to B5 or a 1 mile easy hike via the trail. The backpacking sites are very spread out, we could barely tell anyone else was at the park with us ever.
B5 was beautiful, already lots of mosquitos for May (and appeared poison oak/ivy). I'm not sure what this park does differently than most other parks, but our privy was LOADED with spiders. I get it, it's the outdoors. But still, I've used many in-ground toilets and never had dozens of spiders covering the toilet seat/front.
Another reason we chose this park was for birding. The park ranger at check-in was not helpful and then said he's never heard of MN State Parks free birding kits to borrow, though it's clearly listed on several spots on their website. Bummer, but we still enjoyed our time.
