2009 Gurye Sansuyu Flower Festival (산수유꽃축제): March 19th - 22nd.

In Gurye county, a festival with lots of planned performances---song, dance, drumming---and some flowers thrown in for balance. There is more information via the Gurye county website; the English site says there's a national arm-wrestling competition. Judging by pictures of the festival it looks like a good time.
