🇨🇳 繁體中文版: | English translation of our original Chinese review.
Hey everyone, thanks for tuning in. I’m Rational Travel, a travel blogger who doesn’t do sponsored content and only tells the truth . Once you’ve booked your flights and accommodation for a Seoul trip, the final boss you’ll face is definitely “transportation.”
This post is written for first-timers heading to Seoul or anyone unfamiliar with Seoul’s transit system
Ever notice how the internet is full of contradictory advice? “The subway is super convenient, there’s nowhere it doesn’t go!” “Who takes the subway? The transfers will destroy your knees—it’s basically monk training!” “Taxis are cheap and comfortable, just take them without thinking!” “Buses are king, there’s a stop right outside your place!”
The more information you find, the more your head hurts. So who’s actually telling the truth? Today, Rational Travel is sharing the real talk we’ve learned from actually living here for a while—the “semi-local hot takes(?”, if you will—and breaking down the pros and cons of these three transportation options once and for all.
As usual, before I dive in, let me introduce myself. Not everyone knows who I am, after all.

Is Your Trip Actually Bulletproof?
Most travelers discover missing visas, wrong connections, or closed hotels only after landing. Our 40-point Pre-Trip Audit catches everything — in 24 hours.
Get Your Pre-Trip Audit →Rational Travel’s Take: I usually send flight deals and other money-saving tips to my subscribers first, then publish them publicly after a while, so subscribers can grab them early since many deals have limited time windows and quantities. Obviously, paying subscribers get first dibs.
If you’re the type who buys and sells mileage in Facebook groups or hunts for last-minute hotel deals, Rational Travel’s recently launched ‘a platform with escrow services where you can try first and pay later‘—the Miles Exchange—is now free to my subscribers.
P.S. Subscribers get the complete guides plus lifetime zero-commission access to the Miles Exchange.It’s free now, but I can’t promise that’ll last forever, so… you know what to do. Currently we’ve got close to 2000 subscribers (throwing confetti).
