You know that you have arrived, because the Sunset Café is the last structure on this street, before you look across the Lake at a wide assortment of mountain ridges and at least three volcano peaks.

This lake has been formed in the last couple of years because of the melting of the glacier. The glacier's gone all the way up the mountain and left in its place this big lake.

The mountain last erupted in 1903, but experts cite recent scientific data that suggests Paekdu has an active core that, if it erupts, could cause a huge lake to overflow and flood surrounding areas.
