Yes, during cold weather, Platte River campground is the right choice, even though you have to drive to Lake Michigan and all of the other parts of SBNL. However, in nice weather, DH Day is our all-time favorite campground. Right on Lake Michigan, beautiful campsites. Close to most of the action--Glen Haven, Coast Guard Station, Glen Arbor, etc.--all a short bike ride away on the brand-new bike path that runs through the park. Starting in January, reservations will be possible, which may or may not be a good thing.
