Grjotagjá

The Grjotagjá cave, like many other places near Lake Myvatn, was used for many decades as a natural pool due to the natural properties of its thermal waters. However, when the Krafla Fire eruption occurred in the 1970s and 1980s, the Icelandic authorities were forced to ban the bath in Grjotagjá as temperatures exceeded 60 ° C. The water temperature has now fallen to 43 ° C, but the bathroom is still prohibited. However, it is possible to enter Grjotagjá to enjoy one of the most beautiful volcanic caves in Iceland, in which the thermal lagoon radiates an almost magical blue color.
