Attersee' (also known as the Kammersee) is the largest lake of the Salzkammergut area of Austria. It extends for about 20 km from north to south and 4 km from east to west. Its water comes from the Seeache, which flows out of another lake, the Mondsee.

Attersee is a village located at the western shore of lake Attersee in Upper Austria. The village centre lies between the lake and the slopes of the Buchberg (888 m, 'Beech-mountain') and is the location of a Baroque pilgrimage church from which marvelous views across the lake and up to the "hoellengebirge" (mountains of hell) can be enjoyed.
