If you happen to be based in Busan, or anywhere else in he southeast part on the Korean peninsula really, and you have a couple of days to spare, then the lovely Geoje, an island admired across the country for its stunning nature, is your go-to place.
Geoje is connected to the mainland, so it only takes a relatively short bus ride to take you there. Once there, you can book tours or choose to see attractions for yourself. Among them are the ominous looking, steep-cliffs of the . Next is the lavishly decorated botanical garden that will almost transpose you into a different place for a moment, possibly because of its architecture that is evocative of the Greco-Roman antique era. From here, you can take the lesser known walking path and hike up to the highest point, where you will see a lovely little coffee shop and even more amazing views, probably the best on the island. All in all, definitely worth it for a weekend getaway.
