Pay a visit to Mille Lacs Kathio State Park's Petaga Campground for year 'round awesomeness. From boating and hiking to skiing and sledding, this place always boasts some first-class natural beauty. Spend a few days here, where many of the sites have electric hookups, some are more primitive, and some are private, wooded walk-in sites. You could even reserve one of the heated camper cabins for a ski weekend or a summer vacay to remember. All sites are seconds away from overlooks with killer views, and the river and fish cleaning station is close so you can reel in your dinners with ease.
