What you should know
Hike-in logistics: Backpacking sites require careful planning. At Afton State Park, Adam P. advises: "These sites do require a hike from parking. Would strongly discourage big coolers or lots of weight... They do have firewood available however it is long slab wood, so you do need to cut it yourself."
Seasonal challenges: Bugs can be significant during warmer months. At Lily Springs Regenerative Farm, Krista T. reports, "The mosquito situation was very good, we never even went into our screen house that we had set up just in case it was mosquito misery."
Campsite privacy varies: Site layout and vegetation affect privacy between sites. Dani K. notes at William O'Brien: "Compared to Wild River State Park, the sites at Savannah are pretty cramped with inconsistent vegetation between sites. I wouldn't want to stay here when the loop is fully reserved."
Water availability: Water sources may be limited at certain locations. At Afton State Park, Warren H. warns, "None of the water faucets or water pumps on the trails at Afton State Park are working. The good news is you can fill up on cold drinking water at the visitor center before trekking around the park's beautiful hiking trails!"
Tips for camping with families
Midweek reservations: Weekend sites fill quickly throughout summer. Dani K. shares this strategy for William O'Brien: "My first time solo camping was at William O'Brien State Park on a Sunday evening. Weekends have been packed and reservations scarce for months at state parks in Minnesota."

Tips from RVers
Site selection for small trailers: Several campgrounds accommodate compact RVs despite limited amenities. At William O'Brien State Park, Tim observed, "Although we did not stay in the main campground the sites are very close in there and were small."
