Onondaga County

Onondaga County is an inland administrative region in upstate New York. The county itself does not offer direct seawater diving; water-based activities are focused around nearby freshwater opportunities, notably Lake Ontario, which borders the region to the north. Diving in the area tends to center on inland access, local rivers, and nearby state parks, with limited commercial dive infrastructure within the county. Visitors typically base themselves in Syracuse for access to lakes and other inland aquatic sites, and may combine urban exploration with regional outdoor recreation.
