Altauseerlake has a 6-kilometer long bathing beach and a water temperature of around 25 Celsius in summer. Admission to the lake is free. Facilities include a beach volleyball field, clay tennis courts and rental boats. You can take the MS Erzherzog Johann pleasure cruiser to get to Seewiese-Altaussee.
