I came across BB by accident a few years ago - last minute camping trip in the summer in MN is never going to work out well. The main campground was booked but there was a weird site between the ranger station and the loop so I took a shot. BINGO. They have a site - 31 - that is perfect. About 5x the size of a normal site (perhaps a group site?). No neighbors. Primitive but the campground only has 31 sites so you’re never far away from water, showers, or the ranger station. Cannot recommend highly enough. The main campground backs up to the Tamarack River which flows to Red Lake. Across the road from the camp is Red Lake recreation area. You can w a l k out into the lake for what seems like miles. Very family friendly. There are sites with docks into the river and there is boat access in the campground. Cabins are available as is firewood and an electric charge port for e-vehicles.
