歴史と背景

The cave's geothermal pool was used for bathing by locals for decades until the Krafla eruptions of 1975–1984 raised the water temperature to over 50°C — too hot for bathing. The temperature has slowly dropped and is now around 43–46°C but swimming is still officially discouraged. The cave featured in Game of Thrones Season 3 (2013) as Jon Snow and Ygritte's bathing scene, bringing it worldwide attention.

Nestled in the dramatic landscapes of North Iceland, just a stone's throw from the serene waters of Lake Mývatn, Grjótagjá Cave stands as a testament to Iceland's powerful geothermal activity.

Upon entering Grjótagjá, visitors are immediately struck by the contrast between the rugged, dark volcanic rock and the vibrant, almost surreal blue of the water.
