First Time in Korea? Everything You Need to Do Before You Fly — and Right After You Land

Planning your first trip to Korea? It's easy to lose time at the airport when you have no idea what to do first — where to get a SIM card, whether to exchange money now or later, how to get into the city. Knowing this stuff in advance can make or break your first day. This guide covers everything from pre-departure prep to your very first moves after landing, tailored specifically for first-time visitors.

The difference between a prepared traveler and an unprepared one shows up immediately on day one. Let's go through it step by step.

PART 1 — What to Sort Out Before You Leave

1. Visas & Entry Requirements

Korea offers visa-free entry to citizens of over 100 countries, including the US, UK, Canada, Australia, most of Europe, Japan, and Singapore — typically for up to 90 days. But visa-free doesn't mean no preparation required.

K-ETA (Korea Electronic Travel Authorization)

Since 2021, citizens of certain visa-free countries are required to apply for a K-ETA before traveling. It can be denied just like a visa, and airlines can refuse boarding if you don't have approval.

How to apply: via the official K-ETA website or app
Fee: around USD 10
Processing time: usually within 72 hours, but longer during peak season — apply at least one week before departure
Validity: 2 years or until your passport expires, whichever comes first

✅ Check first: confirm whether your nationality requires a K-ETA. If your country isn't on the list, you'll need a separate visa.

What to Expect at Immigration

An immigration officer may ask:

Purpose of visit (tourism, visiting family, etc.)
How long you're staying
Your accommodation address and contact details

Having your hotel booking confirmation saved on your phone — or printed out — will make the process much quicker.

2. Travel Insurance

Korea has excellent medical care and costs are relatively affordable compared to many Western countries, but as a foreign visitor you won't be covered by the national health insurance system. A routine outpatient visit can run into hundreds of thousands of won, and hospitalization or surgery could easily cost several million.

Key coverage to look for

Medical expenses (minimum USD 100,000)

Emergency evacuation
Trip cancellation / interruption
Lost or damaged baggage
Adventure activities (check if skiing, hiking, etc. are included)

Tips for buying travel insurance

Buy it right after booking your flights, not the night before — that way trip cancellation coverage kicks in from day one
Check whether your credit card already includes travel insurance before purchasing a separate policy
A global travel insurance plan often offers broader coverage than Korea-specific options

3. Money & Cards

Korea has one of the highest rates of card usage in the world. You can pay by card at convenience stores, cafés, restaurants, on the subway, and even at some street stalls. That said, there are still situations where cash is necessary.

Places that may be cash-only

Some stalls inside traditional markets like Gwangjang Market and Namdaemun Market
Small neighborhood restaurants and pojangmacha (street food tents)
Some jjimjilbang (Korean bathhouses) and saunas
Some coin karaoke rooms and arcades

How much cash should you bring?

For a typical week-long trip, around ₩100,000–200,000 in cash should be plenty. Everything else can be handled with your card or ATM withdrawals.

Smart money tips

❌ Airport currency exchange: convenient, but the worst rates you'll find
✅ Myeongdong money changers: the best exchange rates in Seoul, thanks to multiple competing shops in one area
✅ Korean ATMs: ATMs at 7-Eleven, GS25, Woori Bank, and KEB Hana Bank accept foreign cards. There are fees, but the exchange rate is much closer to the interbank rate

Fee-free cards for international use

Cards like Wise, Revolut, and Charles Schwab (US only) let you spend abroad with no foreign transaction fees. Getting one before your trip can save you a noticeable amount.

4. Essential Apps to Download Before You Go

Once you land, you'll need data to download apps — and you'll need a SIM card for data. It's a classic catch-22. Download these before you leave home.

Maps & Navigation

Naver Map — the gold standard for public transit directions in Korea
KakaoMap — integrates with Kakao services, intuitive interface

Taxis

Kakao T — Korea's answer to Uber. Supports English, shows estimated fares upfront

Translation

Papago — made by Naver, significantly better than Google Translate for Korean

Subway

Subway Korea — full metro map with transfer guidance

Air Quality

AirVisual — real-time fine dust (PM2.5) levels

Accommodation

Agoda / Booking.com — compare prices for Korean hotels and guesthouses

Shopping

Coupang — Korea's Amazon equivalent, with same-day delivery

💡 Heads up: Google Maps does not work properly for public transit or walking directions in Korea. The Korean government restricts the export of detailed map data. Naver Map is essential.

5. Packing & Prep Checklist

Power Adapter

Korea uses 220V outlets with Type C plugs (the round two-pin European style). Travelers from the US, Japan, the UK, and other countries will need an adapter. You can buy one at the airport or a convenience store, but it'll cost more — bring one from home.

What to Pack by Season

Spring (Mar–May): Light layers, a mask for yellow dust and fine particle pollution
Summer (Jun–Aug): Light clothing, an umbrella or rain jacket for monsoon season, sunscreen
Fall (Sep–Nov): A jacket is essential — this is the best season to visit
Winter (Dec–Feb): Heavy coat, hand warmers, thick moisturizer (the air is brutally dry)

Medications

Most basic medications are available at Korean pharmacies, but the language barrier can be frustrating. Pack any prescription medication, antacids, pain relievers, and anti-diarrhea medicine from home to be safe. If you take prescription drugs, bring an English-language copy of your prescription.

6. Things to Book in Advance

Popular spots in Korea can fill up fast — especially during peak season in spring and fall. Some things are genuinely hard to get into without a reservation.

Book these before you go

KTX (high-speed rail): Book via Korail (korail.com) or the SRT app. Trains sell out days in advance during peak periods
Popular restaurants: Spots featured on food shows, omakase restaurants, and trendy cafés often require reservations weeks ahead
National park trails: Hallasan on Jeju Island requires advance booking through the national park reservation system
Hanok stays: The best rooms go quickly
K-pop concerts / musicals: Tickets are nearly impossible to get at the door — competition is fierce

PART 2 — What to Do the Moment You Land

1. Getting Through Immigration & Customs

Incheon International Airport is one of the largest airports in the world. Knowing the flow in advance will save you from wandering around lost.

Step-by-step arrival process

Plane lands → make your way to immigration
Immigration: Present your passport plus K-ETA or visa. Fingerprints and photo are taken
Baggage Claim: Find your flight number on the display boards and wait at the correct belt
Customs: Head to the red lane if you have items to declare, green lane if you don't

Customs allowances

Duty-free limit: USD 800 (approximately ₩1,000,000)
Alcohol: 1 bottle up to 1 liter
Tobacco: 200 cigarettes (1 carton)
If you exceed these limits, voluntary declaration means no penalty surcharge

⚠️ Food restrictions: meat products (sausages, ham, jerky, etc.) are prohibited. Getting caught means a fine.

2. SIM Card vs. Pocket Wi-Fi — Which Should You Get?

This is the first thing to sort out before leaving the airport. Without data, you have no maps, no translation, no taxi app — nothing.

Physical SIM Card

Pros: Plug it in and go, fast speeds, affordable
Cons: You'll need to swap out your existing SIM if your phone doesn't support eSIM; check whether your phone is carrier-unlocked
Price: ₩30,000–50,000 for 30 days of unlimited data
Where to buy: Carrier booths (SKT, KT, LG U+) in Terminals 1 and 2, or pre-order online and pick up at the airport

eSIM

Pros: Keep your existing SIM active while using Korean data; purchase online before you travel
Cons: Only works on eSIM-compatible devices (iPhone XS and later, most Galaxy S20 and later)
Recommended services: Airalo, Klook eSIM Korea

Pocket Wi-Fi

Pros: Connect multiple devices at once
Cons: Needs daily charging, you have to carry the device around, losing it means extra charges
Best for: Groups with multiple devices, or if you need to connect a tablet or laptop

✅ Bottom line: If you're traveling solo or as a couple and mostly using smartphones, a SIM card or eSIM is by far the most convenient option.

3. Pick Up a T-Money Card

T-Money is Korea's transit card. It works on the Seoul subway, city buses, taxis, and even at some convenience stores. Grab one as soon as you arrive — you'll want it immediately.

Where to buy

Convenience stores in the airport (CU, GS25): available right after you exit arrivals
Any convenience store nationwide
Ticket vending machines inside subway stations

Price & top-up

Card cost: ₩3,000–5,000 (card issuance fee)
Top-up: Add cash at convenience stores or subway station machines
Loading ₩30,000–50,000 to start is a comfortable amount

The hidden advantage of T-Money

When you transfer between bus and subway within 30 minutes, you get a transfer discount — which you won't get if you pay cash. The more you move around Seoul, the more you save.

4. Getting from the Airport to the City

Incheon International Airport is about 60km from central Seoul. You have four main options.

① AREX Airport Railroad (Most Recommended)

All-stop train: Incheon Airport → Seoul Station in about 66 minutes, ₩9,500
Express train: about 43 minutes, ₩11,000 — reserved seating, more luggage space
Operating hours: 5am to midnight
Stops along the way include Hongdae and Digital Media City

② Airport Limousine Bus

Multiple routes serving different destinations — direct service to Gangnam, Hongdae, Myeongdong, and more
Fare: ₩10,000–18,000
Travel time: 1–2 hours depending on traffic (can stretch to 3 hours during congestion)
Best for: Hotels far from a subway station, or when you have a lot of luggage

③ Taxi

Regular taxi: ₩60,000–90,000 to central Seoul, depending on traffic
Deluxe (black) taxi: ₩80,000–110,000 — cleaner, more comfortable
Can book in advance through the Kakao T app
Best for: Late-night or early-morning arrivals, heavy luggage, when you just want door-to-door

④ Rental Car

Best suited for long-term stays or trips that include Jeju Island
International driver's license required
Rental car desks are located inside the airport

5. Should You Exchange Money at the Airport?

Short answer: exchange the bare minimum at the airport, then go to Myeongdong for the rest.

Airport exchange counters are convenient but offer poor rates. Get just enough for your first transportation costs (₩20,000–30,000), or withdraw a small amount from an ATM, and then change the rest at a money changer in Myeongdong or elsewhere in the city.

Tips for using Myeongdong money changers

Multiple exchange shops are clustered along Myeongdong street — easy to compare rates
Shop around for the best rate before committing
Bring your passport (some shops require it)
Hours: most are open 9am–9pm
