Ellidaa is a river inside the Reykjavik area. Its sources are two smaller rivers in the Blafjoll mountain range and the Hengill area that flow into Ellidavatn and its outlet forms the river.
The river is popular for salmon fishing, though this is quite expensive. On its way, the river flows through the beautiful nature reserve Heidmork.
The Ellidaardalur valley is green and lovely, has a varied birdlife and nearby is an interesting museum telling the story of the electrification of the city.
