GrjótagjáGrjotagja is a small lava cave in the lake Myvatn area in North Iceland. It features a geothermal spring inside.
Grjotagja was popular for bathing until the 1970s but fell out of use during eruptions from 1975 to 1984. The temperature of the water in the cave's pool rised to such a degree that it was not possible to bathe there. However, the tempature is slowly falling down so it is possible to take a bath in the cave now. |
