Linz

Linz is a landlocked city in Austria, not on the coast. The nearby diving options are limited to freshwater environments and training sites rather than coastal diving. The river Maas listed is not in Austria, and likely a data inconsistency; focus in Linz would be on local urban exploration and freshwater dives in closer, properly attributed sites such as quarry or river options in Upper Austria or nearby regions if available. If divers plan, they typically travel to freshwater sites or combine a trip with a coastal destination in neighboring countries.
