Traunsee
Austria's deepest lake, under the wall of the Traunstein, with a castle on an island at Gmunden.
Updated 21 October 2026
The Traunsee is about twelve kilometres long and a hundred and ninety metres deep, which makes it the deepest lake in Austria, held in a steep trough at the northern edge of the limestone Alps with the Traunstein rising to 1,691 metres straight off the eastern shore - a wall that has a long and grim history in Austrian climbing. Gmunden at the north end is a ceramics town, known for the green-striped Gmundner pottery, with Schloss Ort standing on a small island connected by a wooden footbridge, which is the picture everyone takes. Lake steamers have run since 1839 and one paddle steamer from 1871 still operates. Traunkirchen on the western shore has a baroque church with a pulpit carved as a fishing boat and net.
