Taken at inside of Jinjie Cave in Jeju Island, Korea.
I was walking on Olle course 10 in Jeju Island. It connects a couple beaches and mountains along the way. On the south coast of the island, there are these 15 of men-made caves. These 15metres wide and 20metres long are leftovers from the period of when Korea was under Japanese rule. This place is famous for Korean drama film location. The Brothers island are seeing in the background.
