Reichenbach Falls is a series of waterfalls located in the Bernese Oberland region of Switzerland. It is situated near the town of Meiringen and is one of the most famous waterfalls in Switzerland. The falls are formed by the River Aar as it flows through a deep ravine and drops over a series of cascades.

The total height of the falls is 250 meters, and the highest single drop is 120 meters. The falls have been a popular tourist destination since the 19th century, when they were made famous by the fictional detective Sherlock Holmes, who famously plunged to his death at the falls during a confrontation with his arch-nemesis, Professor Moriarty, in the story "The Final Problem" by Sir Arthur Conan Doyle.

The falls are accessible by a funicular railway, which takes visitors to a platform above the falls. From there, a short hike leads to a bridge spanning the falls, providing spectacular views of the cascading water. There are also several hiking trails that lead to various viewpoints of the falls, as well as to the nearby peaks of the Bernese Alps.

In addition to its natural beauty, Reichenbach Falls is also known for its role in Swiss history. During the 18th century, the falls were used to power a sawmill, and later a textile factory, which helped to drive the local economy. Today, the falls remain a popular tourist attraction and a symbol of Switzerland's natural beauty.
