Wisconsin Nude beach
I have visted Mazo Beach on the Wisconsin river and found it to be very friendly . It is clothes optional but no open sex, gay or otherwise allowed. Those actions will be delt with by the other nudist there. I am trying to get my wife to go with me.
You can find it on the web. but it is somewhat hard to find and requires a walk to get from parking to beach.
I was there for the first time in Sept. It was hard for me to find italso. I even knowed aboutit beingon county road Y before you get to Mazomanie. I finally found outthat you takelaws road off of county Y. When you on laws, take the first left and that will be the parking lotfor the beach. After that is a 1.2 milegravel trail to the beach. I highly recommend on bring a bicycle to ride down the trail.
Great beach, haven't been there in a couple years, makes me wish I still lived in Wisconsin. I managed to talk a couple of friends into going a couple times and had a great time. The crowd tended to be a little older than a typical beach in Milwaukee, but still a pretty good diversity of ages (actually more than a handful of college students which is always a good sign) and a good time. Its really too bad we don't have anything like Mazo near the twin cities.
