The arrival of fireflies is a surefire way to know summer is here. This festival celebrates the critters that light up to match the warm and cozy atmosphere of summer nights in the Korean countryside. The best time to see fireflies is at night starting from about 9 pm, and the festival has plenty of other activities to enjoy while you wait, including bare-hands trout fishing and river rafting. For families with children, there are puppet shows and music concerts, and couples can take a romantic evening stroll across the firefly-lit “bridge of love.” Events take place in various locations across Muju.
