Judging by the pictures, there are still quite a few trolls roaming around here in Dimmuborgir. Less charming are the trolls who only leave their caves at night. They can be dangerous to humans.

Dimmuborgir, means "dark cities" or "dark castles" in Icelandic. This formation of volcanic origin near Lake Mývatn contains, among other things, the bizarre lava cave "Kirkja" (church), which is shaped like a Gothic cathedral and also served as the namesake of an Icelandic black metal band.

From this spot, you get a great view of ancient lava columns standing vertically out of the clear blue water. This is a great place to snap a photo before continuing on your hike around this unique geological area.
