Seoul Metro

Charging the Climate Card makes taking the subway so easy. If you're a traveler planning on taking a lot of trips over 3, 5, or 7 days, I definitely recommend buying one! You don't have to check your balance every time, it works everywhere in Seoul, and you can even take the bus, so you can just hop on without a worry!
