Champaign, Illinois, is deep in the North American interior. The nearest ocean coastline is on the Pacific Ocean.
The closest ocean beach is Will Rogers State Beach in Los Angeles, California, approximately 1,850 miles (2,977 km) away by road.
Geographically, the Gulf of Mexico (an Atlantic marginal sea) is closer—about 850 miles to Gulf Shores, Alabama. However, the Gulf is not an "ocean beach" in the strict sense.
For a true ocean experience, West Coast beaches are the destination, albeit a long journey from the Midwest.
