A very large park and very popular, shows signs of use (trash in parking lots and along roadways & trails). Several campground units, we stayed in Riverside Area #1, Site #398 . Sites have good space between each other with thick vegatation, but site was shallow. In our area nearly all sites were pull-through. Park was thick with poison ivy - a concern for those with kids or pets. Several beaches, including one for dogs - nice and sandy. Restroom buildings planned to be replaced in 2009 (according to park staff). Dunes campground seemed tighter - better for tents or smaller units. Great bike trail around park. Many locations for picnics. Park store with small restaurant. We camped here in a Fifth Wheel.
