Haukadalur (Hawkdale) is a name shared by three valleys in Iceland.
Haukadalur, Golden Circle 
There are to be seen some of the most famous sights of the island: the geysers and other geothermal features which have developed on Laugarfjall rhyolitic dome. The biggest geysers of Haukadalur are Strokkur and Geysir itself, which gave others their name. Strokkur is very dependable and erupts every 5 to 10 minutes, whereas the bigger Geysir only erupts 4 to 5 times a day. There are also more than 40 other little hot springs, mud pots and fumaroles nearby.
Haukadalur geothermal area was first mentioned in written sources in 1294, when the local hot springs were activated by earthquake. Earthquakes are known to activate local geysers also in the recent past, including 17th and 21st July 2000 earthquake. Due to geysers the valley has been the prime tourist attraction of Iceland since the 18th century.
The waterfall Gullfoss is about 10 km to the north in the direction of the Highlands of Iceland and at the beginning of the Kjölur highland road. Like Þingvellir, Haukadalur is part of the Golden Circle.
