Jeju Do: Wind, Basalt Rocks and Beautiful Women.
Jeju Do (Jeju Island) is the only Basaltic piece of rock in Korea, so you really ought to visit it. I am so kidding. Actually, Its a small Hawaiian type (Hot Spot) Volcano due south of mainland Korea, and its really worth a visit, if you can make it.
To Koreans Jeju (or Cheju as it is often spelt and how I too often spell it) is famous for four things: Oranges, Basalt, the Mongolian Ponies and beautiful women. But not to be overlooked, Cheju is also the home of the famous diving women; the Haen-nyo, great winds (I experienced a typhoon), stone demarkations or fences, beaches and Pork Pigs that are fed nothing save excrement (they are delicious by the way). Jeju also offers hiking on Halla-san (South Korea's highest peak), some great swimming beaches, and a strange Sloping upward but ACTUALLY downward Road.
Jeju is also Honeymoon Central. Its stepped in tradition, and superstition and along with the noses of the dwarflike guardian granddads it is good luck for Newly Weds. Intrigued? Curious? Come and Check it out?
