Grjótagjá Cave

Grjótagjá Cave is a small lava cave near Lake Mývatn in northern Iceland, renowned for its stunning geothermal hot spring nestled inside. This hidden gem offers a unique experience as visitors descend into the cave’s dark, rocky entrance to discover the crystal-clear, blue waters heated by volcanic activity. The water temperature can vary, often making it too hot for bathing, but the cave itself remains a spectacular sight with its jagged rock formations, dramatic lighting, and steam rising from the water’s surface.

Grjótagjá Cave has a fascinating history, once popular as a bathing spot in the 18th century. However, geothermal activity during the 1970s and early 1980s caused water temperatures to spike, making it unsafe for swimming. While the temperature has since cooled somewhat, it’s still unpredictable, and bathing is generally discouraged.

The cave’s mystical atmosphere has made it a popular filming location, most famously featured in the TV series Game of Thrones, adding to its allure for fans and travellers alike. Whether you’re exploring the cave’s intriguing geological features, capturing stunning photos, or simply soaking in its quiet beauty, Grjótagjá Cave offers a glimpse into Iceland’s captivating natural wonders.
