Main image

Brienzer Rothorn is a 2,350-metre mountain in the Bernese Oberland of Switzerland above Lake Brienz. It is known for panoramic summits and a historic rack railway service.

Hikers and railway passengers reach the summit for wide views over Lake Brienz and the surrounding Bernese Alps; alpine walking routes and the summit plateau are primary attractions. The mountain is popular for day trips in the summer season when the steam railway runs.

The Brienz Rothorn Bahn, a steam-operated rack railway, was established in the late 19th century to provide tourist access to the summit and has operated since then with seasonal service. The mountain itself has long been used for alpine pasture and recreation.

The peak rises above the village of Brienz on the eastern shore of Lake Brienz in the canton of Bern, central Switzerland.

  • Elevation: The mountain reaches an elevation of 2,350 metres, providing extensive views across Lake Brienz and surrounding peaks.
  • Railway access: The heritage steam railway operates seasonally and offers an alternative to the alpine hiking routes for reaching the summit.
