St. Clair County, Michigan

St. Clair County is located in eastern Michigan, right along the shores of the Lake Huron and Lake St. Clair. It’s positioned just across from Canada, separated by St. Clair River.
It’s a place where freighters glide by and folks wave from their front porches. Port Huron is the county seat and is known as the Maritime Capital of the Great Lakes. And for good reason.
The Bluewater Bridge stretches across to Canada, a steel giant connecting two nations. People love the state parks and wildlife areas in this part of Michigan.
