Haukadalur

The geothermal field in Haukadalur, home of the Geysir and Strokkur geysers, is one of Iceland's classic tourist spots. The famous Geysir hot spring (the literal origin of the term geyser) only erupts a few times a year, but the more reliable Strokkur spouts up boiling water as high as 100 feet at five-minute intervals. In the same area there are small natural vents from which steam rises, as well as beautiful, exotic-colored pools. Don't crowd Strokkur, and always be careful when approaching hot springs or mud pots—the ground may be treacherous, suddenly giving way beneath you. Stay on formal paths or established tracks.
