Grjótagjá
Grjótagjá is a small cave in the Lake Mývatn area, and was a popular bathing place at one time. However, geological activity in the period 1975-1984, caused the temperature of the water to rise to such a degree that it has not been possible to bathe there since. But one can always dream ... a peep into the waters and a fertile imagination can conjure up visions of taking a dip in this cosy little cave, as was the custom in the past.
