The first thing we noticed was that the air in Jeju is very refreshing compared to the air in Seoul. This is probably because there are no manufacturing plants in Jeju. Most of the people we've seen here are tourists just like us. Wherever we go, we see at least two other tour buses which means that the sites we visit are almost always crowded. We loved being able to see so much nature on our hikes even though we are always exhausted after! Reaching the top of Seongsun Sunrise Peak and seeing Jeju was well worth the countless steps. Needless to say, we love Jeju!
