Thrihnukagigur
If you find this view badass, hold onto your hat: this is the inside of a volcano’s magma chamber. It is the only volcano in the world where humans can actually enter the chamber. Talk about forbidden—even the image above feels like someone entering the belly of some primordial beast, which is essentially what a volcano is. Thrihnukagigur hasn’t erupted for about 4,500 years, but that doesn’t make the magma chamber any less awesome.
