This is the reason I love Lake St. Clair. Within about 12 miles I can hit just about everything that we like to do, Raft-off in belly deep warm water, tons of restaurants, metro park, nice marinas, and a good friend has a cottage on boat only island we visit. Port Huron approx. 45 miles away. Cedar Point, Put-in-Bay, and Kelly's Island around 70 to 80 miles away. You can stay close or go as far as you like for something fun or relaxing. The lake is usually always calm compared to how Erie and Huron can get. I think St.Clair is a prefect lake to be on.
