Reykjavík Energy owns Elliðavatnsland, which covers a large section of Heiðmörk. On this land, Gvendarbrunn and other water extraction areas of Veitur Utilities, a subsidiary of Reykjavík Energy, are an extremely important resource, providing fresh water to 60% of the Icelandic population.
Heiðmörk is a popular area for outdoor activities on the periphery of the city where varied landscapes are to be found and woodlands which the Reykjavík Forestry Association has cultivated since the middle of the last century in collaboration with Reykjavík Energy and the City of Reykjavík. In many places you will find sheltered coves and lush groves which guests and hikers can enjoy.
There is diversified birdlife in the area, particularly around the Elliðavatn lake and Myllulækjartjörn. Heiðmörk is a good place for berries and the harvesting of mushrooms has increased with the growth of the forest. Hiking paths, which in the winter also serve as skiing and cycling paths, have been laid down.
