On its way to the sea, which is reached in the Elliðavogur bay in Reykjavík, not far from the open-air folk museum of Árbæjarsafn in Árbær, the river cascades over several small waterfalls, within the boundary of the city.
[1] The valley Elliðaárdalur [ˈɛtlɪːðaˌaurˌtaːlʏr̥] is one of the green recreational areas of Reykjavík with hiking and bicycle paths.
Since the beginning of the 20th century, this has been a reforestation area with birch, fir and pine trees planted.
Very interesting and varied bird life is found in the valley including swans and 8 different species of ducks.
The base of the valley is a lava field dating from a volcanic eruption 4500 years ago in the Bláfjöll mountains some 25 km away from the city.
