15 Things I Wish I Knew Before Visiting Korea

I landed at Incheon Airport for the first time with a suitcase full of confidence and absolutely zero preparation. Within 48 hours, I had tried to tip a waiter (awkward), worn my shoes inside someone's home (mortifying), and spent twenty minutes trying to make Google Maps give me accurate bus directions (it won't).

Korea is one of the easiest countries in Asia to travel — the infrastructure is world-class, it's incredibly safe, and the food alone justifies the flight. But there are things that nobody warns you about, and they can turn your first few days from smooth sailing into a series of \"why didn't anyone tell me?\" moments.

Here are the 15 things I wish someone had sat me down and explained before my first trip.

1. You Barely Need Cash — But You'll Still Want Some

Korea is one of the most cashless societies on earth. Credit and debit cards work everywhere — subway stations, convenience stores, taxis, street food vendors, even some vending machines. Samsung Pay and Apple Pay are widely accepted. I've gone entire weeks without touching a single banknote.

But. Some traditional market vendors, especially at places like Gwangjang Market and Namdaemun, still prefer cash. Small pojangmacha tents (those orange late-night food stalls) are often cash-only. And coin lockers at train stations sometimes only take cash or T-money.

What to do: Carry ₩30,000–₩50,000 (~$22–$36 USD) in cash as a backup. You can withdraw from any ATM at a convenience store (CU, GS25, 7-Eleven) or from Global ATMs at banks. Your international Visa or Mastercard will work at most of them.

2. Get a T-Money Card Immediately

A T-money card is a rechargeable transit card that works on every subway, city bus, and even taxis across the entire country. You tap it when you get on, tap it when you get off, and you get discounted transfer fares between subway and bus. It saves you from buying individual tickets for every single ride.

Buy one at any convenience store for ₩2,500 (~$2 USD), then load it with however much you want. I usually load ₩30,000 at a time, which lasts about a week of moderate sightseeing. You can reload at convenience stores or the machines in every subway station.

Pro tip: If your phone supports it, you can get a mobile T-money through the T-money app or use your phone's NFC directly. But a physical card is simpler and works for everyone. Keep it in your phone case for easy tapping.

3. Naver Map, Not Google Maps

This is the single most important tip in this article. Google Maps does not work properly in Korea for navigation. It can show you where things are on a map, but it cannot give you accurate transit directions, walking routes, or real-time bus information. This is due to Korean government mapping data restrictions — it's not a bug, it's policy.

Download Naver Map before your trip. It's available in English, and it gives you perfect subway directions, bus routes with real-time arrival times, walking navigation, and even indoor maps for malls and subway stations. It is the difference between wandering lost for 30 minutes and arriving exactly where you need to be.

Kakao Map is the other option, also excellent, and also available in English. Use either one. Just don't rely on Google Maps.

4. Shoes Come Off — A Lot

You will take your shoes off more than you expect. Restaurants with floor seating (and there are many), traditional guesthouses, temples, some fitting rooms, jimjilbangs, and of course anyone's home. Look for a slightly raised platform at the entrance — that's your cue to remove footwear.

Practical advice: Wear shoes that are easy to slip on and off. Sneakers with excessive laces will become your nemesis. And make sure your socks don't have holes in them. You've been warned.

5. Tipping Doesn't Exist (And Feels Rude)

Do not tip. Not at restaurants, not at hotels, not in taxis, not at hair salons. Korea does not have a tipping culture, and offering a tip can genuinely confuse or offend the person you're trying to compliment. Service staff are paid a proper wage, and good service is simply the standard expectation.

The only exception: some high-end international hotels that cater primarily to Western guests have started accepting tips. But even there, it's not expected. Just say \"mashisseoyo\" (맛있었어요 — \"it was delicious\") at a restaurant, and your server will be happy.

6. The Subway System is Absurdly Good

Seoul's subway is one of the best public transit systems on the planet, and I say that as someone who's used the Tokyo Metro, London Underground, and NYC subway. Trains run every 2–5 minutes during peak hours, every car has heating and air conditioning, the stations are clean, and literally everything is signed in Korean, English, Chinese, and Japanese.

Rides cost ₩1,400–₩2,000 (~$1–$1.50 USD) with T-money, depending on distance. The system runs from approximately 5:30 AM to midnight (slightly later on Fridays and Saturdays). Platform screen doors at every station make it safe and orderly.

Etiquette note: Don't sit in the priority seats (the ones at the ends of each car, usually a different color) unless you are elderly, pregnant, or disabled. Even if they're empty and the train is packed, locals will stand rather than sit there. Follow their lead.

7. Korea Doesn't Sleep

I cannot overstate how late everything stays open. Convenience stores are 24/7 (obviously), but so are many restaurants, cafes, and entertainment spots. In neighborhoods like Hongdae, Gangnam, and Itaewon, you'll find people eating Korean BBQ at 3 AM on a Tuesday like it's the most normal thing in the world — because in Korea, it is.

Jimjilbangs (Korean bathhouses/saunas) are open 24 hours and are a legitimate budget accommodation option. For around ₩12,000–₩15,000, you get access to the baths, saunas, sleeping rooms, and usually a snack bar. Many travelers use them on their last night in Korea when their checkout is early but their flight is late.

8. Bathroom Culture Has a Learning Curve

Two things you need to know:

First: In some older buildings, restaurants, and public bathrooms, you'll see a small trash bin next to the toilet. This is for used toilet paper. The plumbing in older Korean buildings can't handle paper, so you throw it in the bin instead of flushing it. I know. It feels wrong. Newer buildings and most hotels have modern plumbing where you can flush paper normally. When in doubt, check for the bin.

Second: Many public restrooms are located outside individual shops — shared on each floor of a building. If you're in a restaurant and can't find the bathroom, ask for the \"hwajangshil\" (화장실) and they'll point you to the hallway. The bathroom might require a door code displayed near the restaurant entrance or on your receipt.

9. Delivery Culture is Next-Level

Koreans can get virtually anything delivered anywhere. Not just food to your apartment — food to a park bench, to a river bank, to the top of a mountain (almost). The two main delivery apps are Baedal Minjok (배달의민족, often called \"Baemin\") and Coupang Eats.

As a tourist, you'll mostly use these if you're staying in an Airbnb or serviced apartment. The apps are available in English, though the restaurant menus might not be fully translated. Delivery fees are typically ₩1,000–₩4,000 (~$0.70–$3 USD), and food arrives in 20–40 minutes.

Fun fact: Delivery riders will leave your food at your door, on a bench, or wherever you specify. Don't be surprised if you see fried chicken being delivered to people sitting on a blanket by the Han River at 11 PM. That's just a normal Friday.

10. Jimjilbangs Are Worth the Awkwardness

A jimjilbang (찜질방) is a Korean bathhouse and sauna complex. The gender-separated bathing areas require full nudity — no swimsuits allowed. The co-ed sauna and lounging areas provide pajama-like uniforms. Yes, the nudity is initially uncomfortable for most Westerners. Yes, you should go anyway.

Here's the thing: after approximately four minutes, you stop caring. Everyone's naked, nobody's looking at you, and the hot pools, cold plunges, steam rooms, and scrub services are genuinely incredible. A full-body scrub by a Korean ajumma (₩20,000–₩30,000) will remove layers of dead skin you didn't know you had. You'll leave feeling like a newborn.

Famous jimjilbangs: Dragon Hill Spa near Yongsan Station (massive, touristy but great for first-timers), Siloam Sauna near Seoul Station (popular with budget travelers), Spa Land in Busan's Shinsegae Centum City (luxury tier).

11. Korean Drinking Culture is Intense

Koreans drink. A lot. Korea has one of the highest per-capita alcohol consumption rates in the world, and soju (소주) — a clear spirit that tastes like mildly sweet vodka — is the weapon of choice. A bottle costs ₩4,000–₩5,000 at a restaurant and about ₩1,800 at a convenience store.

Cultural rules to know: When drinking with Koreans, never pour your own drink — someone else pours for you, and you pour for them. Receive and give drinks with two hands (or one hand with the other hand supporting your pouring arm). If an elder pours you a drink, turn slightly away from them when you drink it. These are small gestures, but Koreans notice and appreciate when foreigners observe them.

Also: soju sneaks up on you. It goes down smooth at 16–20% alcohol, and before you know it, you've had five shots and the room is spinning. Pace yourself.

12. Convenience Stores Are Actual Restaurants

CU, GS25, 7-Eleven, and Emart24 are not just places to grab gum and a bottle of water. Korean convenience stores are genuine food destinations. The ready-made meals are fresh, cheap, and often delicious — triangle kimbap (₩1,000–₩1,500), cup ramyeon with a hot water dispenser (₩1,200–₩1,500), fried chicken bites, egg sandwiches, and even full lunch boxes (도시락) for ₩3,500–₩5,000.

Most convenience stores have a small eating area with tables and chairs, a microwave, and hot water. Some near universities have become legitimate hangout spots. On a budget day, you can eat three full meals from convenience stores for under ₩15,000 (~$11 USD) total.

13. The Weather Will Surprise You

Korea has four extremely distinct seasons, and the temperature swings are dramatic:

• Spring (March–May): Beautiful, cherry blossoms, mild (8–20°C / 46–68°F). But March can still be genuinely cold. Warning: fine dust (미세먼지, misemeonji) and yellow dust from China are a serious issue in spring. Check the air quality index (AQI) daily using the Naver Weather app or IQAir. On bad days (AQI 100+), wear a KF94 mask — available at every convenience store and pharmacy. Don't pack only spring clothes for an early March trip.
• Summer (June–August): Hot, humid, and monsoon season (장마, jangma) hits in late June through July. Expect heavy rain. August is brutally hot (30–35°C / 86–95°F) and sticky.
• Autumn (September–November): The sweet spot. Perfect temperatures, stunning foliage, clear skies. October is widely considered the best month to visit Korea.
• Winter (December–February): Cold. Properly cold. Seoul regularly drops to -10°C (14°F) in January. But it's beautiful, less crowded, and the best time for winter street food and ski trips.

Pack layers. Even in autumn, mornings can be chilly and afternoons warm. And always carry a small umbrella in summer — rain appears without much warning.

14. WiFi is Everywhere, and It's Free

Korea's internet infrastructure is legendary. Free WiFi is available in every subway station, most buses, all convenience stores, the majority of cafes and restaurants, and throughout major tourist areas. The network is often called \"Public WiFi Free\" or \"KT Free WiFi.\"

That said, I still recommend getting a Korean SIM card or eSIM at Incheon Airport for reliable data everywhere. Providers like KT, SK Telecom, and LG U+ offer tourist SIMs starting at around ₩20,000–₩30,000 for 5–10 days of unlimited data. Having your own data means Naver Map always works, you can call taxis, and you're never stuck looking for WiFi.

You can also rent a portable WiFi device (pocket WiFi) from the airport, which works great for groups. But individual eSIMs have become the simpler option for most travelers in 2026.

15. Learn These Korean Words — Seriously

Korea is not as English-friendly as Japan or Singapore, especially outside Seoul's tourist districts. Learning even basic Korean words will make your trip dramatically smoother and will earn you genuine smiles from locals:

• Annyeonghaseyo (안녕하세요) — Hello
• Gamsahamnida (감사합니다) — Thank you
• Juseyo (주세요) — Please give me [something] (point at menu item + \"juseyo\" = ordering success)
• Eolmayeyo? (얼마예요?) — How much is it?
• Hwajangshil eodiyeyo? (화장실 어디예요?) — Where is the bathroom?
• Mashisseoyo! (맛있어요!) — It's delicious!
• Aigoo (아이고) — General expression of surprise/exasperation (you'll hear this constantly and will start saying it involuntarily within three days)

Bonus tip: The Korean alphabet, Hangul, can be learned in about 2–3 hours. I'm not exaggerating. It was designed to be easy to learn, and being able to sound out signs, menus, and subway stations transforms your experience. There are free apps and YouTube videos that teach it. Do this on the plane ride over. You will not regret it.

The Biggest Thing I Wish I Knew

Korea is wildly underrated as a travel destination. For years, Japan and Thailand dominated the \"Asia travel\" conversation, and Korea was an afterthought. That's changing fast — but even in 2026, Korea delivers an experience that feels less touristy, more authentic, and more affordable than many of its neighbors.

The infrastructure makes travel effortless. The food is extraordinary at every price point. The people are warm once you make even the smallest effort to respect their culture. And the blend of ultra-modern cities with ancient temples, mountain trails, and coastal towns means you'll never run out of things to discover.

Go. You'll wish you'd gone sooner.

Health, Safety & Practical Essentials

• Emergency numbers: Police: 112. Fire/Ambulance: 119. Both accept English calls. Tourist helpline: 1330 (24/7, multilingual).
• Electricity: Korea uses 220V, 60Hz with Type C and Type F plugs (the round two-pin European style). If you're coming from the US, UK, or Australia, you need an adapter. Most hotels provide one, but bring your own to be safe.
• Pharmacies: Look for "약국" (yakguk). Pharmacists often speak basic English and can recommend over-the-counter medication. Common medicines like ibuprofen and cold remedies are available without prescription.
• Water: Tap water is safe to drink in Seoul and major cities, though most Koreans prefer filtered or bottled water. Every restaurant provides free drinking water.

Frequently Asked Questions

Do I need a visa to visit Korea?

Citizens of most Western countries (US, UK, Canada, Australia, EU) can enter Korea visa-free for 90 days for tourism. You'll need a valid passport and a return ticket. Check the Korean Immigration Service website for your specific nationality, as rules can change. As of 2026, the K-ETA (Korea Electronic Travel Authorization) requirement has been temporarily waived for many nationalities — but this can change, so always check the official K-ETA website before your trip, but verify before your trip.

Is Korea expensive to visit?

Korea is surprisingly affordable. A budget traveler can get by on ₩50,000–₩70,000 per day (~$36–$51 USD) including accommodation (hostels or guesthouses), food (convenience stores and street food), and transport (subway). Mid-range travelers spending ₩120,000–₩180,000 per day (~$87–$131 USD) can stay in comfortable hotels, eat at restaurants for every meal, and do paid activities. It's significantly cheaper than Japan for comparable quality.

Is Korea safe for solo travelers?

Extremely safe. Korea consistently ranks among the safest countries in the world. Violent crime against tourists is virtually nonexistent. Women regularly walk alone at night without concern. Public transit runs late, streets are well-lit, and there's CCTV coverage in most public areas. The biggest \"danger\" is probably overindulging in soju.

What's the best time of year to visit Korea?

Autumn (late September through November) is universally considered the best time — mild weather, clear skies, and stunning fall foliage. Spring (April–May) is cherry blossom season and equally lovely. Avoid late June through mid-July if you dislike rain (monsoon season), and be prepared for serious cold if you visit December through February.

Can I get by in Korea with only English?

In Seoul's major tourist areas (Myeongdong, Hongdae, Itaewon, Gangnam), yes — most signs are bilingual and many younger Koreans speak conversational English. Outside these areas and in smaller cities, English becomes much less common. That's why Naver Map and a few basic Korean phrases are so important. Translation apps like Papago (by Naver, far better than Google Translate for Korean) are a lifesaver for restaurant menus and conversations.
