Why St. Clair County, MI

St. Clair County is one of the rare places where major expressways and railways converge with North America’s great inland seaway. As the easternmost of Michigan’s 83 counties, we are an international gateway with the third-busiest commercial truck crossing and busiest rail crossing on the U.S.-Canadian border.

We are a county of 160,000 people, with no town larger than 30,000, spread over 725 square miles.

It may sound slow-paced and sleepy, but we also sit on the edges of a metropolitan area of 3.7 million people. Want to catch a Tigers’ game in downtown Detroit, or check out a popular restaurant in Oakland County? You can be at either in an hour.

Port Huron, our county seat, is precisely halfway between Toronto and Grand Rapids, either of those cities a leisurely three-hour drive. It’s also midway between London, Ontario, and Flint, Michigan, both just an hour away by car. And Port Huron is literally within sight of its sister city, Sarnia, Ontario.

Nothing defines St. Clair County more than our famously blue water.

Our long shoreline includes sandy beaches on Lake Huron, the second-largest of the Great Lakes, and a boaters’ paradise on Lake St. Clair’s 430 square miles. Connecting the two lakes is the 40-mile St. Clair River, the muscular strait that links the upper and lower Great Lakes.

Come and see us, sample what we offer in the way of location, aesthetics and quality of life. Discover the Blue!
