For any of you swimmers in canton of Fribourg, does anyone know of any decent swimming spots around Lac Gruyere, especially for winter swimming, where you can go in off steps or rocks? I do swim in Lac Leman (lake geneva) and have found gorgeous swimming places down there in the likes of Vevay, Lutry, Pully. But I live in Bulle, so Lac Gruyere is closer to me. Thanks. Ken
