Special Offer for Park Permits

Canít decide between a one-day or year-round park permit? The DNR has a special offer that can help. Start by purchasing a one-day permit for $5 and visit as many state parks as possible. After visiting the state parks, trade in the one-day permit by the end of that day and get $5 off the purchase of a year-round permit. Year-round permits, which cost $25, provide unlimited access to all 76 Minnesota state parks and recreation areas for a full year from the month of purchase.
