Brienz
Lake Promenade (1)Lake Brienz is fed by the Aare from the Finsteraarhorn glaciers at 4,275 m above sea level and by the Lütschine rivers from the valleys of Grindelwald and Lauterbrunnen. These rivers carry mineral particles responsible for its colour, which varies with the seasons. Blue in winter, the lake becomes increasingly green as the snow melts.
