Krýsuvík is a geothermal area located on the Reykjanes peninsula in the south west of Iceland. Like many other sites nearby it is located in the fissure zone on the Mid-Atlantic Ridge. The area consists of various geothermal fields with the most famous one being Seltún.
Seltún is also very popular among tourists which is why during recent years wooden pathways have been installed which allow you to safely walk between the numerous fumaroles and mud pots with their boiling water. These wooden pathways allow you to walk a small ring around the area. If you have more time on your hands you can also go for a small hike. Just as always stay on the path, especially in geothermally active areas such as Krysuvik the floor or the water coming out of it can be boiling hot. As usual in Iceland sturdy shoes are always a good idea to be safe and comfortable.
Another reason for the popularity of Krysuvik is the location on the Reykjanes peninsula which makes it ideal to include in the Reykjanes peninsula day tour alongside Kleifarvatn lake, the fishing village Grindavik and the blue lagoon.
This day tour is rather short and can easily be done in 5-6 hours on the way from or to the international airport in Keflavik. But of course it is also worth a while to spend a day visiting this geothermal sensation in the south west of Iceland.
