Harderkulm, Funicular summit station in Unterseen, Bern, Switzerland.

Harderkulm is a mountain peak at 1,322 meters high with views of Lake Thun, Lake Brienz, and the mountains Eiger, Mönch, and Jungfrau. At the top are a restaurant, a terrace, and walking paths that lead to different viewpoints.

The Harderbahn funicular opened on 5 May 1908 and was thoroughly modernised in 1966. Its 1,435-metre line climbs gradients of up to 64 percent and curves almost a quarter-circle, leaving the valley station heading north and arriving at the top heading west. Paths laid out during construction were later extended, and the valley station building survives largely unchanged.

The mountain restaurant serves traditional Swiss Alpine food, and visitors can enjoy the views through large windows while eating. The terrace is a popular gathering spot where hikers and day-trippers stop to take in the surroundings.

The Harderbahn funicular runs from Interlaken to the upper station, a five-minute walk from the restaurant, in eight minutes. The line is 1,435 metres long and climbs gradients of up to 64 percent, curving almost a quarter-circle from a northward start to a westward finish.

The Harderbahn climbs 1,435 metres of track and overcomes gradients of up to 64 percent, yet instead of running straight up it curves through almost a quarter circle, leaving Interlaken heading north and arriving at the top facing west. The upper station sits about five minutes' walk from the restaurant.
