St. Tammany Parish

St. Tammany Parish lies along the northern shore of Lake Pontchartrain and extends toward the Gulf of Mexico, offering limited recreational diving within its administrative boundaries. The region is better known for its coastal access and nearby dive options along the Louisiana coast and across the Gulf of Mexico, including Gulf-facing sites reachable from larger urban centers. Inland waters, marsh habitats, and riverine environments characterize the area, with more active diving opportunities found in adjacent parishes and coastal towns along the Gulf of Mexico.
