Aarau

Aarau is a small inland city in northern Switzerland. It sits away from the sea and has no local sea diving. Nearby water-based options are limited to freshwater training or nearby lakes and quarries outside the city area, but diving here is not a primary draw. The city serves as a regional hub with good transport links to larger Swiss dive centers and classic Alpine landscapes, making it a practical base for travelers who want to continue diving in other parts of the country or neighboring freshwater sites.
