Twin Falls, Natural waterfall in Southern Idaho, United States.
Twin Falls is a waterfall on the Snake River in southern Idaho, dropping into a deep canyon carved through layers of volcanic basalt rock. Just above the drop, the river splits into two separate streams that fall side by side, which is how the site got its name.
The area around the falls was used by Shoshone people for fishing, particularly for salmon, long before settlers arrived. In the early 20th century, dams were built on the Snake River upstream, which changed the volume and appearance of the falls over time.
The waterfall sits right next to the city that shares its name, making it a familiar backdrop for local life. People come here to walk along the rim and look down into the canyon from the viewing platforms.
The falls are viewed from the rim of the canyon, where paved paths and open overlooks make it easy to get a clear view without climbing down. Visiting on a weekday or in the morning helps avoid crowds, especially during summer.
Despite having two falls in its name, only one is usually visible today because much of the river's water is diverted for irrigation upstream. Both falls can be seen at the same time only when the river runs unusually high, typically in spring.
