Ludentarborgir is a crater row east of Lake Myvatn, about 15 meters long.
The best way to visit this area is on a relaxed self drive tour. One of the best options for doing so is this 7-day Arctic Coast Way self drive, available in the summer months.
These craters take their name from the explosion crater Ludent, to their north east. The astronauts of space shuttle Appolo 11 trained for their mission in the lunar landscape of Ludentarborgir. The two southernmost craters are known as Threngslaborgir, and that name is often used for the whole crater row, or at least the southern part.
A volcanic eruption in the crater area created the Stora Laxarhraun lava field some 2300 years ago. The lava field covers some 220 km2 and is home to such attractions as the famous Dimmuborgir and the Skutustadagigar pseudocraters.
