25 things to know before visiting Seoul

Most “things to know before visiting” lists are recycled between cities with the city name swapped in. This one is specific to Seoul: the apps that actually work here, the palace rule that trips up almost every first-timer, and the transport quirks that aren’t obvious until you’re standing at the wrong subway exit. Twenty-five items, roughly grouped by when you’ll need them.

Before you land

1. Google Maps doesn’t work properly here. South Korea restricts export of high-precision mapping data, so Google Maps can’t give reliable walking directions, transit routing, or turn-by-turn navigation inside the country. Download Naver Map or KakaoMap before you land — both have full English interfaces. The full explanation, including a 2026 policy shift that may eventually change this, is in why Google Maps doesn’t work in Korea.

2. Check whether you need a K-ETA. Korea’s electronic travel authorization is currently suspended for travelers from around 22 countries, including the US, UK, most of the EU, Australia, and New Zealand — but the rules have a stated end date and could change. Check your specific situation before booking flights in the K-ETA Korea 2026 guide.

3. You’ll fill out an e-Arrival Card regardless. Even travelers exempt from K-ETA still need to submit Korea’s digital arrival declaration before landing — paper forms have been phased out.

4. Decide on a SIM or eSIM before arrival. Airport counters charge roughly double what booking online ahead of time costs. An eSIM activated before you land also means you have data the moment you step off the plane.

5. Know which airport you’re flying into. Incheon (ICN) is the main international gateway; Gimpo (GMP) handles domestic and some regional international routes and sits closer to central Seoul. Confirm which one your itinerary uses — see Incheon vs Gimpo airport.

Money and transport

6. Get a T-money card immediately. It’s the universal transit card — subway, bus, some taxis, and convenience-store purchases all run through it. Buy one at any convenience store on arrival, or set up a mobile version before landing. Full details in the Seoul metro & T-money guide.

7. Cash still matters more than you’d expect. Cards are widely accepted, but some markets, small restaurants, and transit passes (like the multi-day tourist pass) still run on cash or require KRW top-ups. Carry some.

8. There’s no tipping. Not at restaurants, not for taxis, not for tour guides. Attempting to tip can occasionally cause more confusion than goodwill.

9. Base rate for the subway is 1,550 KRW, with free transfers between subway and bus within a 30-60 minute window (up to four transfers a day). It’s one of the best-value transit systems of any major capital.

10. Consider a multi-day transport pass if you’re moving a lot. Passes bundling unlimited transit with some attraction discounts run from about 15,000 to 64,500 KRW depending on duration — worth pricing against your itinerary before assuming pay-per-ride is cheaper.

11. Taxis are metered — insist on it. If a driver quotes a flat fare instead of using the meter, say “miteo-ro haejuseyo” (please use the meter) or find another taxi. Late-night fares (10pm-4am) run 20-40% higher, which is normal, not a scam.

12. Restaurant menus should have prices posted. Tourist-area restaurants without visible pricing have been a documented source of complaints — double-charging a visible-menu item to a tourist versus a local at the next table isn’t rare. Full detail in Seoul taxi & restaurant scams.

Palaces, culture and etiquette

13. Gyeongbokgung is closed on Tuesdays. It’s Seoul’s most-visited palace and the one with the guard-changing ceremony, and the Tuesday closure catches a surprising number of first-timers who build a tight itinerary without checking. Other palaces keep different closure days — never assume they match. Full breakdown in palace closure days.

14. A full hanbok gets you free palace entry. Rent a complete hanbok — top and bottom — and you skip admission at Seoul’s five royal palaces. Partial or “hanbok-inspired” outfits may not qualify. See the hanbok rental guide.

15. The last Wednesday of the month is “Culture Day.” Free entry to palaces and several museums for everyone, no hanbok required. Worth planning around if your dates are flexible.

16. Use “Gyeongbokgung Palace,” not “Gyeongbok Palace.” Korea’s Cultural Heritage Administration recommends the full romanized name plus an English suffix — minor, but it’s the correct form and will help you match signage and search results to what you’re looking for.

17. Don’t stick chopsticks upright in a bowl of rice. It echoes a funeral ritual and reads as disrespectful, even unintentionally.

18. Use two hands when giving or receiving something from someone older. A small gesture, but a noticeable one — a slight nod while doing it helps too. More on everyday etiquette mistakes in Korean etiquette mistakes.

19. Keep your voice down on public transit. Phone calls, loud conversations, and playing audio without headphones are more noticeably out of place here than in many Western cities.

Food and daily life

20. Convenience stores are a real meal option, not a last resort. CU, GS25, and 7-Eleven sell genuinely good instant noodles, triangle kimbap, and hot food, with seating at many locations. See the convenience store food guide.

21. Street food markets have a real food scene, not just souvenirs. Gwangjang Market in particular is a legitimate destination for bindaetteok, mayak gimbap, and knife-cut noodles — not a tourist trap dressed up as one. See the Gwangjang Market food tour guide.

22. Jjimjilbangs (bathhouses) have real etiquette rules. Full nudity is standard in the gender- separated bathing areas; the shared common areas require the provided uniform. First-timers benefit from reading up before going. See jjimjilbang etiquette.

23. July and August are the season to plan around, not toward. Jangma (the rainy season) and peak heat overlap, with heavy humidity and heat-wave risk. Late September to mid-November is the strongest weather window; late April to early May for cherry blossoms is the second-best. Full breakdown in best time to visit Seoul.

Logistics that surprise people

24. Seoul’s neighborhoods are more spread out than the metro map suggests. A “-gu” is a district (like Mapo-gu), a “-dong” is a neighborhood within it (like Seongsu-dong) — understanding the difference makes addresses and directions much less confusing. See Seoul neighborhoods explained.

25. Book DMZ tours further ahead than you’d think. The JSA (Panmunjom) portion specifically needs a reservation 5-7 days in advance with a passport copy, and is closed Sunday and Monday. A generic DMZ tour without the JSA portion is more flexible. Don’t leave this one for your last free day — see the DMZ/JSA tour guide.

A few more things that don’t fit neatly into a list

Pharmacies are everywhere and reasonably priced. Green-cross-signed pharmacies (yakguk) are common in every neighborhood, and pharmacists in central areas often speak at least functional English. Over-the-counter versions of common medications are cheap and don’t require the paperwork some countries expect.

Public restrooms are cleaner and more common than most first-timers expect. Subway stations, department stores, convenience stores, and parks all have accessible public restrooms — carrying your own tissue is still a good habit, since some public restrooms don’t stock it consistently.

Recycling and trash sorting is taken seriously. Public trash cans are less common on the street than in many cities, partly because household and public waste sorting rules are strict. Don’t be surprised if you have to carry a wrapper for a few blocks before finding a bin — convenience stores usually have one near the entrance if you’re stuck.

Air quality varies by season. Fine dust levels (hwangsa, often blown in from the mainland) can spike in spring, less commonly in other seasons. It’s rarely severe enough to change travel plans, but checking a daily air quality app is a reasonable habit if you have respiratory sensitivities.

The emergency number is 112 for police, 119 for fire and medical. The tourist information hotline 1330 is a separate, dedicated line for scam reports, general questions, and interpretation help — save it before you land rather than looking it up mid-problem.

Charging outlets are Type C/F (European-style, two round pins). Bring an adapter if you’re coming from a country using a different plug standard — hotels rarely stock spares for guests.

Frequently asked questions about visiting Seoul for the first time

What’s the single biggest mistake first-time visitors make in Seoul?

Relying on Google Maps for walking or transit directions. It genuinely doesn’t work reliably here — switch to Naver Map or KakaoMap before your trip starts, not after you’re lost.

Do I need cash in Seoul, or is it card-only?

Cards are widely accepted, but keep some cash for markets, smaller restaurants, and certain transit passes that require KRW top-ups.

Is Seoul safe for first-time visitors?

Yes, by most standard safety measures — it ranks among the safer major capitals globally. The real risks are more mundane: tourist-priced restaurants and unmetered taxis rather than personal safety.

How far ahead should I plan a Seoul trip?

Two to three months ahead if you want a JSA reservation on a specific date, or if you’re traveling during cherry blossom or autumn foliage season, when hotel prices climb. Otherwise, a few weeks of lead time is enough for most of the city.

What should I download before I land?

Naver Map or KakaoMap, plus a T-money mobile card if your phone supports it. Both save real time on your first day compared to figuring them out after arrival.
