At Krýsuvík is a stunning and striking landscape. Dramatic yellow, red and green hills. Steaming volcanic vents. Boiling mud and a smell of rotten eggs due to the volcanic gas coming out of the earth. It is an exciting place. You have the feeling the next volcanic eruption can happen any moment.
In fact, it can happen any moment. It is a highly volcanic active area on the Atlantic ridge separating North America and Europe.
There is a big geothermal spring full of boiling black smelly mud. Its name is Fúli Pottur (Smelly Pot). You are not allowed to go near it. The mud is boiling and very dangerous.
Close by the smelly hot springs is a beautiful turquoise-green lake. Its name is Grænavatn (Green Lake). The color of the water is due to volcanic ingredients. This is actually a volcanic crater. Formed by an explosion eruption.
