Strokkur is an active geyser that can be found along with other geysers, fumaroles and mud fields in the Haukadalur geothermal area. Nearly 1.5 million tourists come here every year, and they all want to see the little miracle of water gushing high out of the ground.
The way it’s done is quite interesting. The point is that water which, due to pressure, has a temperature higher than 100°C can no longer withstand its volume and explodes. And since he has nowhere else to go, he’s gushing into the air.
Strokkur is not the only geyser in the area. Just a few tens of metres away is Geysir geyser, but it is not reliable and its last known eruption was in 2009.
Strokkur, on the other hand, is very active and you can expect an eruption of 20-25 about every 5-8 minutes. Interestingly, double and sometimes triple eruptions are no exception.
Strokkur is probably the most famous natural attraction in Iceland. Together with Þingvellir National Park and Gullfoss Waterfall, it is part of the so-called Golden Circle.
