The Reichenbach Falls are a waterfall cascade of seven steps on the stream called Rychenbach in the Bernese Oberland region of Switzerland. They drop over a total height of about 250 metres (820 ft). At 110 metres (360 ft), the upper falls, known as the Grand Reichenbach Fall, is by far the tallest segment and one of the highest waterfalls in the Alps, and among the forty highest in Switzerland. The Reichenbach loses 290 metres (950 ft) of height from the top of the falls to the valley floor of the Haslital. Today, a hydroelectric power company harnesses the flow of the Reichenbach Falls during certain times of year, reducing its flow.

The Oberhasli is a historical Landvogtei or Talschaft in the Bernese Highlands, Switzerland, bordering on the cantons of Obwalden (OW), Nidwalden (NW), Uri (UR) and Wallis (VS).
