Campers' Paradise is island camping that you get to by driving across a 1 lane road to get to the island.  There are lakefront sites or interior sites but this is as close to beach front camping as you will get in MN!  The lake front sites have their own sandy walk in to the water.  The sites are separated by trees/brush so you feel that they are really private.  There's a nice beach/play area for the kids and the bathrooms are really clean.
