We noticed on the trail app that most of the trails stopped where they were close to the Dunes, but this park doesn't actually let you climb the natural dune area. There was a trail that led right up to the beach though.
If there is it is not marked on the existing trail map. I have noticed though a couple old pathways off the main trail from the parking lot they have purposely cut off with railings and added signage to asking people not to go off the marked trails in order to preserve the dune ecosystem. All trails on the map are loops that bring you back to main trail that goes from parking lot to beach.
