The probably most romantic part of Brienz is the Brunngasse which, having once been awarded the title «most beautiful street in Europe», is well-known abroad. Most of the houses in the street date from the 18th century and are decorated with wood carvings.

The most beautiful street in Brienz, and arguably one of the most picturesque in all of Switzerland, is the Brunngasse. This historic street is world-famous for its traditional, ornate 18th-century wooden chalets, which are decorated with intricate woodcarvings—a craft for which Brienz is the national center. During the summer months, the residents of Brunngasse adorn their balconies with overflowing window boxes of bright red geraniums, creating a scene that looks like a living postcard. The street has been honored as the "most beautiful alley in Europe" in various travel accolades. Beyond the Brunngasse, the Seepromenade (the lakeside promenade) offers stunning, unobstructed views of the turquoise Lake Brienz and the surrounding Bernese Oberland mountains. However, for that quintessential "Swiss village" charm with cobblestones and ancient timber architecture, the Brunngasse is the undisputed highlight. It is a very short walk from the Brienz train station and the pier, making it an essential stop for anyone visiting the Interlaken region in 2026.
