On the Heron Lakeside of the park (south side of the road), there is a bathhouse that opens all year round. Just go inside and wait for another guy to come inside. Very private area. Since these directions and descriptions suck… when you pull into the park keep going straight past the booth and take it all the way back. It’s quite a drive, you’ll cross over a bridge over the lake and everything and its oaks flats. Like I said it’s quite a drive from the entrance
This is a Michigan State Park and requires a "Passport" shown on the vehicle plate sticker. There is a bathhouse and changing facilities near the public beach. Just go inside and wait for another guy to come inside. Make the normal signals. Since many people use this changing area you will need to find more private areas on the trail or many parking facilities.
