Vibrant colors ablaze, crisp temperatures, and less traffic make autumn an outstanding time to visit Voyageurs. Visitors can enjoy the changing fall colors as they hike trails or cast their fishing line. However, fall can be a short season in Northern Minnesota and cold temperatures arrive quickly. Near the end of September, boaters and paddlers should be aware of cold-water temperatures. In addition, park buoys are typically removed in early October, making lake navigation challenging.
