We booked our stay at the Lower Campground on a whim as it was one of the only campsites available in MN on a two week notice during Covid. It turned out to be a pleasant surprise! The park is perfect for a short weekend trip. Campground was well maintained with easy access to the hiking trails and a nice view of the lake. There was enough exploring to fill a day or two. The sites are close side-to-side, but trees line the outside sites and there is good back-to-back space between the inner sites. Not all sites have hammock trees though. We got very lucky with the August weather as the bugs were completely manageable both at the campground and on the hikes. The Lower Campground is the only one with electric sites, but the Oak Ridge had nice shade and space. Preferred sites in Lower Campground would be 7 for non-electric for privacy and lake views, and 14e, 16e, and 18e for electric. Bathrooms were not open for use when we came. Also, the water fill and dump stations are on the opposite side of most campers which was the only downside. There was not water supply at the dump station to rinse out the tank. But overall, it’s nice trip that’s only two hours from the Twin Cities. We enjoyed the prairie views and the lake. Will be back!
