Great State Park. The beach area is huge, so there is plenty of room for families to swim, picnic, or just look at the scenery. Lots of mature trees around that make it feel like you are in a forest. The grounds and restroom areas are very well maintained. There are plenty of picnic tables and grills to go around for everybody. It's nice that there are picnic areas that are away from all of the hustle and bustle of the beach and boat launch. There is lots of truck and trailer parking for those who bring boats as well. Hayes is also a nice place for people who like to hike. Another nice feature of the beach area is that they have a concessions stand and a place to rent beach floats and other items. You can purchase sunscreen, snacks, and drinks at the concessions stand, too. It's definitely worth the trip to go out there. It's one of the nicest state parks in Michigan that we've been to.
