Ohio

Ohio is primarily a freshwater region, with most diving focused on the Great Lakes and inland lakes and quarries. The dive scene includes small, community-centered shops and shore-and-boat-accessible sites around coastal-adjacent areas, but overall diving options are limited compared to traditional coastal destinations. Expect cool water, variable visibility, and freshwater species typical of temperate North America. The region offers basic dive training and local exploration rather than destination-level underwater attractions. Access is straightforward from Midwest hubs, with several small centers serving local divers.
