Wisconsin has several nudist resorts, and they're not hard to find. But you may want to know what you're getting into before you pop into a thread-free zone and peel off your wrapper among strangers. Fortunately, there are ways to get your feet wet while dressed to the eyeballs, if you wish. Then again, if you want to dive in headfirst, it's easy to find out where to do it.
Check websites that list Wisconsin nudist resorts to learn what's out there. Such sites include Nudist Resorts and Nudist Escapes.
Join a nudist chat group such as the Clothes Free Forum and gain the benefit of others' experiences at Wisconsin resorts. You can do this without even showing your face, let alone the body parts you're used to hiding.
Join a Wisconsin nudist organization, such as The Badger Naturists or Valley View Recreation Club, when you reach a sufficient comfort level. They can provide you with all the information you want as well as hosting events where you can network with those who know the scene.
Book a stay at one of Wisconsin's nudist resorts and find out for yourself. You'll be happy you did, or not.
