Top 20 Things to Do on Jeju Island

Jeju Island has been my home away from home for the last year or so.  And when the weather warms up around May, I am quite ready to see all that I can see as summer swings in.  Jeju is considered the "Hawaii" of Korea and with several UNESCO World Heritage Sites, I am continuously amazed by the serene and beautiful sites that make up Jeju Island.  It took some time figure out where everything was, so I thought, I'd put together a list of the top 20 things to do here on Jeju.
