Located on the eastern seaboard of Korea's Jeju Island, Seongsan Ilchulbong is a tuff cone formed by hydrovolcanic eruptions some 5,000 years ago. The northwestern portion is a Seongsan Park, where I took this photo of the edge of the crater. I think it's a rather dreamy place, with a small beach brushing up against a rather dramatic cliff.
In retrospect, Jeju Island wasn't the best planned trips of mine, although there was some planning. When I arrived on the island at the my hotel, it was maybe 8am. I hired what was at that time one of three English speaking taxi drivers to drive me around the island for the day at the rather reasonable rate of $120 for the day (~8 hours).
This was one of the many sights I got to see on my taxi tour. Jeju Island is filled with a million different tourist traps, both natural and man-made that you can easily fill your days with. I only spent 3 days which wasn't really enough. Hopefully I'll be able to make it back again sooner than later.
