    When Grjótagjá in Game of Thrones was featured, the cave became a must-visit destination for fans. In season three, episode five, Jon Snow and Ygritte share an intimate moment in this cave. As expected, tourists soon flocked to Grjótagjá, eager to experience the show's magic.

    What Are the Geological Features of Grjótagjá Cave?

    The Grjótagjá lava cave is a geological marvel formed by volcanic activity for centuries. This underground cavern boasts intricate lava formations, indicative of its fiery origin. 

    However, the cave's most striking feature is the radiant blue spring hidden within its depths. The spring gets its heat from the nearby Krafla volcano, making the water warm enough to have been used for bathing in the past. 

    Combining these geological features creates a unique and picturesque setting, making Grjótagjá a must-visit spot.

    What's the Historical Significance of Grjótagjá?

    Grjótagjá's history is as intriguing as its geology, tracing back to the early 18th Century. This hot spring cave was once a sanctuary for Jón Markússon, an outlaw who sought refuge in its secluded depths.

    The cave's dark environment and local superstitions about trolls kept most Icelanders away, allowing outlaws like Jón to dwell undisturbed. After Jón's passing, the cave shed its ominous reputation. It transformed into a beloved local hot spring, becoming a must-see on any Iceland itinerary

    How Did Grjótagjá Become The Game of Throne Cave?

    The transformation of Grjótagjá into the Game of Thrones cave can be traced to a significant moment where protagonists Jon Snow and Wildling Ygritte consummate their relationship. 

    This intimate episode, which saw Jon Snow 'proving' his abandonment of the Night's Watch, catapulted Grjótagjá into global fame. Soon after the airing of this scene, there was a surge in tourism, with fans eager to visit one of the key Game of Thrones filming locations in Iceland

    The influx of visitors led to challenges preserving the cave's natural beauty, causing its closure in 2018. However, it has since been reopened to the public, allowing fans to experience this piece of Westeros in the real world.

    How Can You Get To Grjótagjá Cave?

    Reaching Grjótagjá in Iceland is an adventure in itself. Located near the renowned Lake Mývatn, the cave is about a 6-minute drive from the town of Reykjahlíð. You could travel via Route 1 (Ring Road) and then take Route 860 for a more scenic drive. 

    This route forms a part of the illustrious Diamond Circle, encompassing attractions like the Dettifoss Waterfall and the Húsavík town. For convenience, consider making Reykjahlíð your base, as it offers easy access to various attractions and the chance to immerse yourself in the Icelandic experience truly.

    Why is Bathing in Grjótagjá Prohibited?

    Understanding why bathing is prohibited in Grjótagjá requires diving into the cave's history. Historically, locals cherished the cave's warm waters. However, between 1975 and 1984, the Krafla volcanic system superheated the water to boiling temperatures. 

    Since then, due to nearby geothermal activity, the water temperatures in Grjótagjá have been unpredictable, often exceeding 50°C (122°F). This unpredictability, combined with the potential risks of temperatures that can scald, led to the prohibition of bathing in the cave. While immersing oneself in the same waters as Jon Snow might be tempting, the risks are real.
