On the ground
The Lake Superior National Estuarine Research Reserve protects a freshwater estuary where the St. Louis River meets Lake Superior. Designated in 2010, this area—spanning approximately 16,697 acres—is co-managed by NOAA and the University of Wisconsin-Madison. It’s significant because its wetlands filter runoff, buffer the lake, and provide vital habitat for fish and migrating birds.
RV travelers can explore miles of paddle trails and boardwalks within the reserve. These pathways offer access to expansive wetlands that are home to diverse birdlife, native plants, and various fish species. Paddlers will find a quiet environment ideal for observing the unique ecology where freshwater meets one of the Great Lakes.
The best time to visit is from late spring through early fall. Bird migration peaks in May and September, offering excellent viewing opportunities. Summer provides warmer weather suitable for paddling and exploring the estuarine areas. Conditions during these months allow for comfortable access to reserve features.
Establish a basecamp in the vicinity to explore the Reserve at your own pace. From there, short trips can be made to access various points within the estuary. This allows RV travelers to experience the unique ecosystem while maintaining the convenience of a central location.
