Korea Travel Checklist

Why I Made This Checklist

I'm Korean, and I travel abroad often — mostly Europe and Japan. Every single time, it's the same story: there's a long list of things to prepare, and no matter how carefully I plan, I still forget something. A SIM card. The right currency. A visa detail I assumed didn't apply to me.

That's the exact problem this page is meant to solve — not for me this time, but for people coming the other way, into Korea. The checklist above is the short version, the one you can screenshot and check off at the airport. Below is the longer version: the reasoning behind each item, and the mistakes that trip people up most often.

Visa & Passport

Not every visitor needs a visa to enter South Korea — but "do I need one" isn't a yes/no question, it depends on your nationality and how long you're staying. Citizens of many countries get visa-free entry for short stays (commonly 30–90 days depending on the country), but the exact number of days varies, and overstaying even by a day can cause problems at your next entry.

Two things people miss most often: passport validity (most airlines and immigration checks want at least 6 months of validity remaining from your entry date, not your return date), and K-ETA. K-ETA is a separate electronic travel authorization that some visa-exempt nationalities are still required to apply for online before departure — it is not the same thing as a visa, and skipping it because "I don't need a visa" is one of the most common mistakes. Apply for it a few days before you fly, not at the airport.

Cash & Currency

Korea is more card-friendly than it used to be, but it isn't fully cashless. Small restaurants, traditional markets, some taxis, and coin lockers still expect cash, and a foreign card doesn't always work smoothly on local card readers or T-money transit top-up machines. A reasonable rule of thumb: bring enough Korean won in cash to cover 2–3 days of small purchases, and rely on a card (ideally one with no foreign transaction fee) for everything else.

Currency exchange counters at the airport tend to have worse rates than exchange offices in Myeongdong or Hongdae, so if your flight lands late at night, exchanging a small amount at the airport just to get through the first day — and doing a proper exchange in the city the next day — usually works out better than exchanging everything at once at the airport.

eSIM or Physical SIM

This is a genuinely practical decision, not just a preference. An eSIM can be activated before you even land, which means you have data the moment you step off the plane — useful if you're navigating immigration, finding transport, or meeting someone. A physical SIM or pocket wifi, bought at airport kiosks or picked up on arrival, is usually a little cheaper for longer trips but means you're offline until you pick it up.

If your phone supports eSIM (most phones from the last few years do) and your trip is under two weeks, eSIM is generally the simpler choice. For longer stays, or if you're traveling with a phone that doesn't support eSIM, a physical SIM bought locally is usually more cost-effective.

Weather & What to Pack

Korea's seasons are more extreme than many visitors expect. Summer (June–August) is hot and humid, closer to Southeast Asia than most of Europe. Winter (December–February) can be genuinely cold, especially in the north and inland areas, with wind that makes the actual temperature feel colder than the number suggests. Spring and fall are shorter and milder, but the gap between morning and afternoon temperatures can be significant.

Rather than packing based on the season name alone, check the actual forecast for your travel dates a few days before departure — Korea's weather can shift faster than a general seasonal guide accounts for, especially around monsoon season (roughly July) or early snow in late fall.

Plug & Voltage

Korea uses 220V with Type C/F plugs (the two-round-pin European style). If you're traveling from North America, the UK, or most of Asia outside East Asia, you'll need a plug adapter at minimum. Devices that only support 110–120V (some older hair dryers or straighteners, for example) will need a voltage converter, not just an adapter — plugging a 110V-only device into 220V without one can damage it. Most modern electronics (phone chargers, laptops) are dual-voltage and only need the adapter.

If you don't already own one, a basic Type C/F plug adapter covers any dual-voltage device. If you're traveling from continental Europe, you likely already have a compatible plug and don't need one at all — see the Plug & Voltage Checker for whether you need a voltage converter too.

Airport Arrival

After landing, the general order is: immigration, baggage claim, customs, then the arrivals hall. If you applied for K-ETA or a visa in advance, have the confirmation ready (a screenshot is usually fine, but a saved PDF is safer in case you lose signal). From Incheon or Gimpo, the most predictable way into the city is the airport railroad (AREX) or a licensed airport bus — both have clearly marked counters in the arrivals hall, and prices are fixed, unlike some unmarked taxi services that approach travelers before they reach the official taxi line.

For which of those actually fits your situation — arrival time, luggage, group size, and where your hotel is — see Incheon Airport to Seoul, including what to do if you land after the last train or bus.

Local Transport & Emergencies

A T-money card (available at convenience stores and subway ticket machines) covers subway, bus, and even some taxis, and is worth getting on day one rather than buying single tickets each time. For emergencies, 112 is police and 119 is fire/medical — both have English-speaking operators available, though there can be a short wait to be connected to one. It's worth saving both numbers in your phone before you need them, not after.

Since you'll likely be leaning on maps, translation, and transit apps most of the day, a compact portable battery is worth packing so you're not hunting for an outlet mid-trip. Skip it if your phone already comfortably lasts a full day of navigation and photos.

Tax Refund

If you're not a Korean resident and you shop at stores displaying a Tax Free sign, you can usually get a VAT refund on purchases over a minimum amount (this threshold and the refund process can vary by store type). Refunds are typically processed at the airport before departure — either at self-service kiosks or refund counters — so keep your receipts and the tax refund forms given at checkout, and allow extra time at the airport if you're planning to claim a refund rather than assuming it will take five minutes.
