Crow Wing State Park

There are some very nice trails here (14 miles!), including steps directly from the campground down to the Mississippi River, making this a good state park to camp at for a few days. There are 61 sites, 12 of which are electric. The sites with no hookups on the outer loop and not next to trails probably have the best privacy (21, 22, 25, 26, 27, 28) but the road out has no-hookup sites separated with trees from other sites so they're good too (32-39). As far as electric sites go, there's very little privacy.

If it looks like there's plenty of spots open, I say just show up and register the one you think looks best from your phone. Otherwise, no site is better than the rest, just try to book a site not next to an occupied one. 16e had good privacy, but being next to the restroom/shower building means there's more people walking by and being loud. Ice and wood for sale at the main office, and there's a dump station.

The big negative here (or nerdy positive, if you're interested in gawking) is that the state park is across the river from Camp Ripley, so military planes frequently fly over, even during the middle of the night, and they're loud.
