We tried some street foods when going to Seongsan Ilchulbong, one of UNESCO World Heritage.
Do you know that Jeju is habitat for enormous colony of cacti? They're all naturally grown on Jeju volcanic soil. On this post, I'll write about variety of cosmetics & foods made from Jeju local cactus and its fruit.
We strongly suggest you to buy Transportation Card (T-money) to go around Jeju. Paying bus/taxi with cash is acceptable, but paying with card will cost you less (the fare is cheaper rather than paying with cash). Moreover, it will be more convenient to just tap to the machine everytime you enter and exit bus, rather than taking out money from your purse in hassle.
