From Harder Kulm, you can enjoy panoramic views of two distinct lakes: the deep blue Lake Thun and the vibrant turquoise Lake Brienz. These two magnificent bodies of water are nestled amidst the majestic Bernese Alps.
Lake Thun is characterized by its deep blue, clear waters and is the largest lake entirely within a single canton in Switzerland. It is surrounded by high peaks of the Bernese Alps and is renowned for its five historic castles along its shores, including Thun Castle and Spiez Castle. The impressive St. Beatus Caves are also located by Lake Thun.
Lake Brienz is famous for its exceptionally clear, greenish-blue, or 'milky teal' turquoise waters, a result of glacial meltwater. It is nestled amidst dramatic mountain landscapes, and the stunning Giessbach Falls cascade directly into it. Picturesque villages like Brienz and Iseltwald dot its shores.
Yes, Lake Thun is rich in history and culture. Its shores are home to five historic castles: Thun Castle, Oberhofen Castle, Schadau Castle, Hünegg Castle, and Spiez Castle. These castles offer a glimpse into the region's past and are popular attractions.
Yes, boat cruises are a popular way to experience both Lake Thun and Lake Brienz. You can explore charming lakeside towns and villages, and on Lake Brienz, you can even get a close-up view of the Giessbach Falls from the water. The Interlaken Ost Boat Terminal serves Lake Brienz.
Many activities around the lakes are suitable for families. For instance, the Two lakes footbridge - Harder Kulm viewing platform is easily accessible via funicular and offers incredible views. Exploring the St. Beatus Caves near Lake Thun is also a unique underground adventure for all ages. Designated swimming areas are available in both lakes during warmer months.
The region offers a variety of hiking trails.
