10 Things I Wish I Knew Before Traveling to Seoul (2026 Local Tips)
⚡ Quick Answer: Before you land in Seoul, know this: Korea is almost fully cashless (but keep some Won for street food and T-money top-ups), Google Maps doesn't do walking directions here (use Naver Map or KakaoMap), tipping is not expected anywhere, and public trash cans are rare. Add an eSIM, a 220V plug adapter, and the habit of tapping your T-money card on and off, and you'll move through the city like a local.
Planning a trip to Seoul is exciting, but navigating a country with its own digital and cultural landscape can catch Western travelers off guard — from map apps that don't work to unwritten dining etiquette. To make your trip seamless, here are 10 things I wish I knew before visiting Seoul, with the practical hacks that actually matter on the ground.
1. Seoul Is Almost Cashless — but Carry Some Won
South Korea is nearly cashless. You can tap an international Visa or Mastercard at the vast majority of restaurants, cafes, and convenience stores. You'll still want a little Korean Won (₩) cash for two things: topping up your T-money transit card at convenience stores (those top-ups are cash only — though newer subway station kiosks now accept foreign cards), and buying treats at street-food markets like Myeongdong or Gwangjang, where many stalls take cash only.
2. There Are Almost No Public Trash Cans
One of the first things you'll notice is how few public trash cans there are on the streets — a policy meant to cut down on illegal dumping.
The hack: Keep a small plastic bag in your daypack for trash. When you need to toss it, look inside subway stations, public restrooms, or the convenience store where you bought the item.
3. Tipping Is Not Expected (and Can Be Awkward)
If you're coming from the US, leave your tipping habits at home. In South Korea, tipping is simply not part of the culture. The price on the menu is exactly what you pay — tax and service are already included. Leave extra cash on the table and a server may well chase you down to return it.
4. Google Maps Doesn't Work — Use Korean Apps
Because of mapping-data export restrictions, Google Maps won't give you reliable walking directions in Korea.
The hack: Download Naver Map or KakaoMap before your trip, and use Kakao T (not standard Uber) to call local taxis without a language barrier. For the full rundown of what to install, see our 5 Essential Apps for Korea Travel.
5. Korean Dining Is Communal (K-BBQ, Banchan & Solo Tips)
Korean food culture is deeply communal. Many traditional spots — especially Korean BBQ (K-BBQ) or bubbling stews like budae-jjigae — require a minimum order of two servings to start.
The hack: Solo travelers should look for dishes served individually, like bibimbap or gukbap (rice soups), or head to cafe hubs and convenience stores where eating alone is completely normal. And yes — all those little side dishes (banchan) are free and refillable.
6. Free Wi-Fi Is Everywhere, but Get an eSIM Anyway
Seoul has some of the best public Wi-Fi in the world, in subways, cafes, and on the street. The catch: many public networks ask for a Korean phone number to authenticate.
The hack: Don't rely on public Wi-Fi alone. Buy a cheap data eSIM or rent pocket Wi-Fi at Incheon Airport so your navigation apps work in real time the moment you land.
7. Subway & Escalator Etiquette
Seoul's subways are quiet and orderly. To blend in like a local: on escalators, stand on the right so people in a hurry can pass on the left. Inside the cars, keep conversations low. And never sit in the priority seats at the ends of each car — they're reserved for the elderly, pregnant women, and people with disabilities, even when the train is packed.
8. Pack a Plug Adapter (Korea Runs on 220V)
Korea uses 220V power with round two-pin plugs (Type C/F), the same as most of continental Europe.
The hack: Travelers from the US, UK, or Japan need a plug adapter. Most phone and laptop chargers handle 220V automatically, but double-check higher-wattage items like hair dryers and styling tools, which can burn out without a voltage converter.
9. Take Your Shoes Off Indoors
At traditional restaurants with floor seating, guesthouses, hanok stays, temple stays, and in Korean homes, you remove your shoes at the entrance.
The hack: Watch for a shoe rack or a raised step up from the floor — that's your cue to take them off. Wearing socks you don't mind showing saves a little awkwardness.
10. Convenience Stores Will Save You
CU, GS25, 7-Eleven, and Emart24 sit on nearly every corner and run 24/7. They're far more than snack shops: it's where you top up your T-money card, grab a cheap hot meal (staff will heat it for you), buy an umbrella when the rain hits, and find "Global ATMs" that accept foreign cards for cash withdrawals.

Frequently Asked Questions
Do I need cash in Seoul, or is a card enough?
A foreign Visa or Mastercard covers almost everything in Seoul. Keep a small amount of Korean Won for street-food markets and for topping up a T-money card at convenience stores, which is cash only.
Do I tip in restaurants and taxis in Korea?
No. Tipping is not customary anywhere in Korea. The menu or meter price is the full price, with tax and service already included, so there's no need to add anything.
Why doesn't Google Maps work in Korea?
Korea restricts the export of detailed mapping data for security reasons, so Google Maps can't provide full walking or driving directions. Use Naver Map or KakaoMap instead — see our 5 Essential Apps for Korea Travel.
What power adapter do I need for Korea?
Korea uses 220V with round two-pin plugs (Type C/F), like most of Europe. Bring an adapter if you're coming from the US, UK, or Japan, and check the voltage rating on high-wattage devices such as hair dryers.
Do I need to speak Korean to travel in Seoul?
No. Subway signs, station names, and many menus include English, younger locals often speak some English, and a translation app like Papago bridges the rest. You can navigate Seoul comfortably without Korean.
