Free Fun Weekend is June 1-2 in Wisconsin. Residents and visitors can fish, hike or bike state trails, enjoy admission to state parks and forests and ride public ATV trails.
No fishing license is needed to fish any waters. This includes inland trout and Great Lakes trout and salmon fishing, which normally would require a trout stamp in addition to a license. Fishing rules such as limits on the size and species of fish that can be kept do apply.
All state trail pass fees on all DNR-owned state trails are waived and cooperatively-run state trails also may waive fees.
