Grænavatn is a small lake on the Reykjanes Peninsula, known for its vivid colouration.
Explore this area while on a self drive tour in Iceland.
The name translates to ‘Green Lake’, and as it suggests, the lake is dyed a seafoam green due to the amount of sulphur in it, as well as its surprising depth of 45 metres (148 ft). The closer to the centre of the feature, the more intense the green.
