Attersee – Ofen (többször lezárva / repeatedly closed)
Repeatedly closed by the authorities – check the current status before diving. The Ofen entry lies in the municipality of Steinbach on the east shore of the Attersee, near the Salzburg border. Its steep walls drop sharply into deep water where visibility is often poor and the temperature only a few degrees, and the site is known for serious accidents among divers going very deep. After a diver went missing in 2018 the security authority ordered a diving ban for the site, and after another accident in June 2025 the site and the neighbouring entries were temporarily closed again.
