Grjótagjá
Grjótagjá is a small lava cave located near lake Mývatn in north Iceland with a geothermal hot spring. It was used by locals for bathng until the 1970s, when Iceland’s unpredictable geothermal forces prevented them from doing so: from 1975 to 1984 the Krafla volcanic system erupted several times, making the water in the cave boiling and therefore unusable. After 1984, the temperature has slowly cooled, but has been known to rapidly heat again. In the surrounding area, liquid rock is just two kilometres under the surface of the earth, meaning it can be very unpredictable. As such, bathing is no longer allowed in Grjótagjá.
