Two important “GoT” filming locations can be found in the Lake Myvatn area which is known for its bizarre yet starkly beautiful volcanic features. This is where you’ll find Grjótagjá, the small lava cave that served as Jon and Ygritte’s “love nest,” the very spot where Jon lost his virginity on the show, and the scene that sparked a real-life relationship between the actors themselves, Kit Harington and Rose Leslie. While the cave is surrounded by ice and snow much of the time, inside, the spring can get as hot as 120 degrees Fahrenheit, which may explain at least part of the reason Jon and Ygritte were so hot. The Dimmuborgir lava field served as the Wildling Camp and is famous for its unique rock formations that give it the appearance of being a different planet.
