Oedolgae Sea Stack sits not far from the shores of Sammaebong Peak in Seogwipo. It is an amazing rock 20 meters in x_height and is estimated to have formed approximately 1.5 million years ago. The fantastic rocks of the coastal cliff around Oedolgae and Sammaebong Peak provide the perfect background for trekking. The sunset of Beomseom Island, which can be seen from Oedolgae Sea Stack, has long been an admired view for people visiting Jeju Island.
