The lake has an area of about 12.9 to 13.1 km² and is surrounded by the Salzkammergut mountain range. On the northern side, the Schafberg is located. A rack railway, the Schafbergbahn leads up to the summit at 1,782 m. Due to the steep shore at its foot only a footpath connects St. Wolfgang and the village of Ried with St. Gilgen along the Falkensteinwand, the set of the Bergpsalmen (mountain psalms) lyric anthology written by Joseph Viktor von Scheffel in 1870. In the south and southwest of Lake Wolfgang lies the Osterhorngruppe, with heights up to 1,800 metres. Directly south of St. Gilgen rises the Zwölferhorn (1,521 m), which can be visited by cable car.
