Known as Brienzersee or Lake Brienz, Lake Brienzer provides fine views of the Bernese Alps. Visitors who come to Lake Brienzer find they are swimming in one of the cleanest and clearest lakes in all of Switzerland. Lake Brienzer offers them the city’s specialty woodcarving. Lake Brienzer can then show you Interlaken. Interlaken lies between two lakes. It has a Castle Church, the beautiful landscaped grounds around Kursaal and a “Mystery Park.” Erich Von Däniken, the UFO writer, designed the park complete with natural and supernatural sections. For something totally different, however, you can visit the historical open-air museum of Freilichtmuseum Ballenberg to catch a glimpse of the region’s past.
