Jeju Seongsan Ilchulbong – A Gigantic Crown
Rated as a World Natural Heritage by Unesco, Seongsan Ilchulbong is for you all the nature lovers out there. This gigantic crown like mountain was formed by volcanic activities and regarded as a holy mountain(Seong-san) by the local since many years ago. In fact the locals at the old days bow 4 times towards it as they passed by. Be early if your hotel is far away like mine(at Jungmun). If took us almost more than an hour drive because there are just too many speed traps on Jeju island. After I parked my rented car, I can’t see the mountain is actually in a con shape(bird view) as described. 
Rock is 1 of the 3 abundants in Jeju island beside women and wind. If you like all the 3 abundants including rocks, then Yong Duam and Oedolgae Rock should be in your itinerary. Anyway, these 2 place is not near to each other – Yong Duam rock is near to Jeju airport while Oedolgae rock near to Seougwipo City. You may want to drop by these 2 places if you happen to pass by. The reason I said so is because you won’t spend much time here and some might not enjoy rock watching especially Yong Duam rock. There is not much to do and see at Yong Duam but it’s an iconic tourist spot for picture taking and scenic sea view would make it worth a 30 mins stop by.
