Scuba Certification in Illinois


Illinois is most well-known for its metropolis, Chicago. However, due to its proximity to Lake Michigan and many other lakes, Illinois is a great state for scuba diving. In addition to Lake Michigan in general, some of the more popular dive sites in Illinois include Haigh Quarry, Pearl Lake, and the wreck of the Rotarian. Access at some dive sites may be restricted, or may require a diver be scuba certified to dive at that site. Be certain you check site-specific requirements before attempting your dive.
