Grjótagjá is a mesmerizing lava cave and hot spring located in North Iceland. Known for its stunning, blue geothermal waters nestled within a cavern formed by volcanic activity, Grjótagjá has become a popular, albeit secluded, destination for adventurers and history enthusiasts alike.
One of the most unique features of Grjótagjá is its small, clear blue hot spring inside the lava cave. This charming pool reaches temperatures between 45-50°C, providing a warm, enchanting retreat from the cooler Icelandic climate. The cave itself, with its dramatic rock formations and cracks, was made famous by the hit TV series 'Game of Thrones,' where it served as a filming location.
Perched in the geothermal Mývatn region, Grjótagjá is easily accessible from the Ring Road (Route 1). Situated just a short distance from Lake Mývatn, it offers an unforgettable experience amid a landscape dotted with volcanic craters, bubbling mud pots, and steam vents.
Nearby, visitors can explore the spectacular Hverfjall crater, a tephra cone open for hiking, or the mystical Dimmuborgir lava formations, often referred to as the Dark Castles. The Mývatn Nature Baths, a relaxing alternative to the Blue Lagoon, are also in close proximity, allowing visitors to soak up more of Iceland's geothermal wonders.
