I used to work at this state park for two years and really enjoyed my time there. I spent many nights there with family and coworkers. The staff is very friendly and they patrol all through the night to ensure safety and noise control. The sites vary from close together, to secluded. It is easy to camp in a group with sites all close to each other, or to be off on your own. the bathrooms on the campground side are very clean. They are newer and updated and are cleaned 2-3 times a day or more as needed. The visitor side has less updated bathrooms, making them appear more dirty, but they are cleaned 4-6 times a day at the least. These bathrooms are also close to the beach, so sand makes it seem dirty as well. Sites vary in size, allowing tents or large rvs to be in most spaces. This campground does get very full most weekends Memorial Day through Labor Day, especially around the 4th of July. Bay city has lots to do and the visitor side has plenty of interesting programs for kids to do. swimming is iffy, as the city closes the beach depending on bacteria in the water and which way the wind is blowing it on a given day. The water is not clean (not the parks fault). there is a splash pad for younger children to enjoy though. There are no water sites. you must cross a relatively busy road to get to the visitor side where the beach/splash pad/visitor center is.
