The word geyser is derived from the Great Geysir. However, Geysir is very unreliable these days. Strokkur, on the other hand, with its reliable eruption cycle has become a more popular tourist destination. Strokkur is a fountain geyser located in the geothermal field in the Haukadalur valley in Iceland. Nearby are located many smaller geysers (as well as the Geysir).
Strokkur was supposedly set off during an earthquake in 1789. It is a very energetic geyser, the water sprouting around 10-20m high. At any time of the day, you can see rings of tourists, cameras in hand, waiting for the geyser to erupt. And Strokkur doesn’t disappoint; it erupts every 8-10 minutes sending fumes of sulphur your way if you stand in the direction of the wind.
