Belle Isle Park
Belle Isle Park is an inner-city island retreat with twenty miles of walkways, sports facilities, a marina, and free attractions including an aquarium, a Great Lakes Museum, and elaborate gardens. It is quiet during the week but can attract crowds on the weekend. Belle Isle Park is also home to the annual Detroit Grand Prix Indy car race. To see the island, use Diamond Jack's River Tours (early June to early Sept; $15;
