Fossa (river)

Fossá is the name of several rivers in Iceland that are known for their waterfalls. The most well-known is Fossárdalur, which runs from Þingvellir towards the southern side of Hvalfjörður. This river is characterized by numerous waterfalls, with the most popular one located near Route 47, where car parking is available.

There are other rivers in Iceland with the name Fossá, such as Fossá in Kjós and Fossá in Berufjörður, which are located in the Eastern Region (Austurland) near the fjord Berufjörður.

The term "Fossá" is derived from the Icelandic words "foss" meaning "waterfall" and "á" meaning "river." It is a common name for rivers in Iceland that feature waterfalls.
