State Natural Areas within State Parks, Recreation Areas and Southern Forests While entry to most State Natural Areas is free, some sites require that visitors have a vehicle admission sticker because they are located within Wisconsin state parks, recreation areas or forests charging admission fees. However, on Free Fun Weekend, June 1-2, 2019, admission fees are waived at all state park properties so you may visit the embedded State Natural Areas for free. To learn more about these sites, search by State Natural Area name.
