The Great Lakes Bay Regional Trail is a non-profit organization dedicated to linking Trails in the Great Lakes Bay Region of Michigan (Bay, Midland and Saginaw Counties). Once completed, our Regional Trail will be close to a 100-mile system that will give walkers, runners, cyclists and skaters access to some of our region's best, from green spaces to parks and recreational facilities...even waterfront views of Lake Huron's Saginaw Bay!
