The tall rock sticking out of the water on the left side is called Oedolgae (외둘개), and is a really impressive site to see! Somehow, it doesn't look as impressive on film, but it wasn't possible to go down lower to really show its size.
My friends and I went out on the stones to the right of it, and it was amazing to see how big it is, and also to get such an amazing view of the sea. The photo I posted last week (http://www.vingle.net/posts/363296-Clash-of-Blues) was taken from the cliffs on the right side! You can see the top of Oedolgae in that photo.
