Today the park's attraction is the Strokkur, which in Icelandic means "child". Strokor is located just a few meters from the largest geyser and erupts at regular intervals of five minutes or so. A strong jet of boiling water rises to the sky and reaches a height of 40 meters, a truly unforgettable sight for those watching.
Some speculate that the geyser was formed at the end of the 13th century when a series of strong earthquakes accompanied the fatal eruption of the Hekla volcano, hit the Hoiikadalok Valley causing geothermal activity. The entire geyser valley is a geothermal park that sits on top of a huge cauldron of boiling water.
All around, water, mud and sulfur bubble from openings in the earth and occasionally the whistling sound of steam can be heard. The colored mud is the result of bacteria and primitive plants that thrive in these hostile conditions. Some, like the bacteria generated, live at a temperature of 60 ° in hydrogen sulphide environment, which lets off a smell of rotten eggs and gives the ground a greyish color.
A short distance to the west is Laugarfjall Hill. Although small in size, the hill has spectacular panoramic views of the geysers park. King Christian IX of Denmark, visited the area in 1874, and while leaning on a rock at the foothills, his guests tried to impress him by boiling eggs in the hot springs. Since then these rocks have been called "The King's Stones".
