Grjótagjá Cave

Jón Markson, an outlaw, stayed there in the early 18th century and bathed in the cave. Grjótagjá was a popular bathing spot until the 1970s. However, during the eruptions from 1975 to 1984, the temperature of the water reached to much over 50 °C (122 °F), though the temperature has since dropped below 50 °C. Stóragjá, a neighboring lava cave, is being used as an alternative swimming location.

Grjótagjá is a stunning hot spring cave that you may recognize from the Game of Thrones television series. Fans of the show will recognize this as the location where John and Ygritte were filmed getting steamy together. The cave was said to be home to trolls by the Old Icelanders. We don't have any proof, but we know that the Icelandic outlaw Jon Markusson lived in the cave and bathed in the boiling springs during the 18th century. Bathing in the hot springs here is no longer possible due to a succession of volcanic explosions. The fluctuating temperatures are dangerous, and you should not attempt to enter the water. The caves, on the other hand, are breathtaking and should not be missed. As the water vapor wraps around your limbs like smoke, have a seat on the ancient rocks and hear about the famous trolls.
