What Travellers Say
Reviews Summary
Visitors find Grjótagjá Cave a visually stunning, albeit small, natural wonder, particularly appealing to Game of Thrones fans. While the cave's interior is dark and requires careful navigation, the vibrant blue geothermal spring is a highlight. Many appreciate the surrounding geological formations and the potential for aurora viewing, though some feel it's best as a quick stop rather than a dedicated destination.
"If you're already in the area and you have extra time, this is an interesting place to visit. I wouldn't make a special trip for it though since it's small and you may have to wait to see inside. We went in the evening last month and it wasn't too crowded. I can see why Game of Thrones was filmed here though. The geology is fascinating."
Terri Sanne
"A lot of people come here because of the Game of Thrones series. I haven’t seen the show myself, and still found the place absolutely spectacular. We went early in the morning and had the entire area to ourselves. At night, we returned to the parking lot to watch the northern lights, and it was a great decision—there’s no light pollution at all, making it a perfect spot for aurora viewing."
Marc Roca
"It's a beautiful one to do a quick pit stop . It has parking and the path to the cave is rocky so wear good shoes and also on a 10 meter walk up the cave where you can see earth separation after an earthquake"
