Seongsan Ilchulbong Tuff Cone is a volcano situated at the end of Seongsan Peninsula on the east of Jeju Island. It got its name, "Seongsan" because of the ninety-nine rock precipice that surround its crater like a giant castle. It is famous for its sunrises. 
성산일출봉은 제주 동쪽에 돌출한 성산반도 끝머리에 있는 화산으로, 분화구 위는 99개의 바위 봉우리가 빙 둘러 서 있어 그 모습이 거대한 성과 같다 하여 "성산"이라 하며, 해돋이가 유명한 일출봉입니다. (출처: 오설록)
There are a lot of stair on the way up.....
​More Stairs......
Aaannddd...more Stairs....
​Luckily there is an AED ready just in case you have a heart attack.
By the time we reached the top, we had missed the sunrise and were exhausted from the ridiculous amount of stairs......we were not happy.
On the bright side there was a cool air hose at the bottom to clean your shoes....so not everything was bad.
