For a first trip to South Korea, plan on 7 to 10 days, go in spring or autumn, start in Seoul and add either Busan by bullet train or Jeju by short flight. Confirm your K-ETA position and install a Korean map app before you fly, and almost everything else can be decided on the ground.
South Korea rewards a little planning and punishes almost none of it. You can land in Seoul with nothing booked and still have a wonderful trip, thanks to one of the best public transport systems on earth and a country that runs on convenience. But a handful of decisions made before you fly are the difference between a smooth first visit and one spent solving problems on the ground: when to go, how to split your days between the capital, the coast and the island, and what to reserve early. This is the guide we wish someone had handed us the first time.
When is the best time to go to South Korea?
Korea has four sharply defined seasons, and two of them are close to perfect. Which one suits you depends on what you want from the trip.
Spring and autumn: the easy choice
Spring, from late March to May, brings cherry blossoms, mild days and a country in bloom. Autumn, from late September to November, brings crisp air, golden light and some of the best foliage in Asia. Both are ideal for city walking and mountain hikes. The catch is that everyone else has the same idea, so flights and good-value rooms go first. Blossom and foliage timing shifts a little from year to year, so choose a window rather than a single date, and book rooms with free cancellation where you can.
Summer: hot, humid and festive
Summer, June to August, is hot, humid and includes a rainy stretch called jangma. It is also festival season and the best time for Jeju beaches. Choose it if beaches matter more to you than comfortable sightseeing, and plan indoor breaks in the middle of the day.
Winter: quiet cities, hot water
Winter, December to February, is cold and dry, quiet in the cities but excellent for skiing and steaming outdoor spa pools. It suits travellers who dislike crowds and do not mind layering up. If you can pick, aim for the shoulder seasons and read our season-by-season guide for the details.
Public holidays
Korea’s big national holidays, such as Lunar New Year and Chuseok, send much of the country travelling at once, so trains, roads and domestic flights fill up. The dates change each year, so check them before you fix your plans and book intercity transport early if you overlap.
Do you need a visa or K-ETA for South Korea?
There are two separate questions here, and mixing them up is how people end up at the check-in desk with a problem.
Question one: do you need a visa?
For most readers, no. Tourists from the US, UK, Ireland, most EU countries, Australia and New Zealand enter visa-free for up to 90 days; the exact number of days depends on the passport, so check yours. Canadians get an unusually generous six months. South Africans are also visa-free, but for a shorter 30 days, so a long southern-Africa-to-Asia trip needs planning around that.
Question two: do you need a K-ETA?
The K-ETA is Korea’s online travel authorisation, applied for before departure and, once approved, valid for three years and multiple entries. Visa-free visitors normally need one. However, Korea has been running a temporary waiver for a named list of roughly two dozen countries and territories, among them the US, UK, Canada, Australia, New Zealand, Japan, Singapore, Taiwan, Hong Kong and much of Western Europe, and that waiver has been extended to the end of 2026.
The catch is that the waiver list is specific rather than regional. Ireland is not on it, so Irish passport holders still need to apply, as do travellers from several other European countries and from South Africa. The application is quick and cheap, but approval is not instant, so allow a few days rather than doing it at the airport.
A simple order of operations
- Find the official K-ETA portal yourself rather than following a link from an ad or a forum, so you know you are on the real government site.
- Check your own nationality against the current waiver list, not a friend’s.
- If you need to apply, do it as soon as your flights are booked, with your passport details entered exactly as printed.
- Print or screenshot the approval and keep it with your passport.
Because both the list and its expiry date have been extended and revised repeatedly, check your own nationality on the official K-ETA portal before you book anything.
How many days do you need in South Korea?
| Length | A shape that works | What you give up |
|---|---|---|
| 4 to 5 days | Seoul, with a day trip | The rest of the country |
| 7 days | Seoul plus Busan, or Seoul plus Jeju | The other one |
| 10 days | Seoul, Busan and Jeju, unhurried | Very little |
| 14 days | All three plus Gyeongju or the mountains | Almost nothing |
The rule underneath every row: move fewer times than you think. Korea is compact and its transport is superb, which tempts people into five stops in ten days, and the result is a lot of very efficient travelling and not much sitting still.
Which length suits you?
- Five days or fewer: treat it as a Seoul trip with one outing. Our five days in Korea sets out the realistic first-timer plan, including what to leave out.
- A week: pick Busan or Jeju, not both, and resist adding a third stop.
- Ten days: the sweet spot for a first visit, with room for the capital, a southern city and the island without a rushed morning. Our 10-day route through Seoul, Gyeongju, Busan and Jeju does exactly this.
- Two weeks or more: slow down rather than add more places. Spend longer outside the capital, and let the weather decide a day or two.
With a week or more, the route most first visits settle into runs Seoul, Gyeongju and Busan, in that order and for good reasons. Our classic Korea itinerary explains why the middle stop is the one people cut and why they regret it.
Seoul first, then the rest
Give Seoul three full days
Almost every first trip starts in Seoul, and it should. Give it at least three full days: the grand royal palaces and the hanbok crowds around them, the hanok lanes of Bukchon, the shopping and street food of Myeongdong and Insadong, and a night out in Hongdae or Itaewon. Seoul is also the hub from which the fast trains and flights fan out across the country. A useful rhythm is old Seoul by day (palaces, lanes, markets) and the newer, louder neighbourhoods after dark.
Busan or Jeju?
From Seoul, the two classic additions are Busan, the relaxed southern port city reached in under three hours by KTX bullet train, and Jeju, the volcanic holiday island a short domestic flight away. For a first week, pair Seoul with one of them. For 10 days, do both, and put Jeju last so the trip ends slowly rather than in a city.
| Busan | Jeju | |
|---|---|---|
| Feel | Big coastal city, beaches and seafood | Island pace, volcanic scenery |
| Getting there from Seoul | KTX, roughly two and a half hours | Short domestic flight |
| Best for | Food, markets, city energy with sea air | Coastal walking, nature, slowing down |
| Best season | Spring, autumn and summer beach days | Summer beaches, but good all year |
| Downside | Still a city, so less of a change from Seoul | A car genuinely helps outside the main town |
Our guide to Jeju covers what the island actually offers, which is volcanic landscape, coastal walking and the best seafood in the country rather than a resort holiday.
How to get around South Korea
Korea makes this easy, but a few habits save time on day one.
The T-money card
Buy a T-money card at any convenience store or station machine, top it up, and tap onto subways, buses and even some taxis nationwide. On the metro and buses, tap in as you board and tap out as you leave, which keeps transfers working properly. Seoul and Busan both have clean, cheap, English-signed metro systems that reach almost everywhere a visitor wants to go.
Between cities
The KTX high-speed rail is the star: Seoul to Busan in roughly two and a half hours, comfortable and punctual. It is also easier to book than most rail systems, and our guide to KTX trains in Korea covers routes, classes and whether a rail pass pays. For Jeju, you fly, and the Seoul to Jeju route is one of the busiest air corridors in the world, so tickets are frequent and often cheap.
Maps and navigation
This is the one place Korea catches first-timers out. Google Maps does not give full walking directions here, so install a Korean map app such as Naver Map or KakaoMap before you leave, and download an offline area if you are heading beyond the big cities.
Do you need a car?
You rarely need to rent one unless you are exploring Jeju or the countryside, where it genuinely helps. If you plan to drive, check the licence requirements for your own passport with the relevant official source before you book, rather than assuming your home licence is enough.
Turn travel days into guided onesA small-group day tour reaches the temples, coastlines and villages that are awkward to reach on your ownWhat to book ahead, and what to leave loose
Book early
Book your first two nights so you land somewhere sorted, your hotels for cherry-blossom and autumn-foliage season (the good-value rooms vanish first), your domestic flights to Jeju if your dates are fixed, and any headline experiences like a DMZ tour, which must be booked in advance and cannot be visited independently. Sort an eSIM or a pocket wifi too, so you have data and maps the moment you clear the airport.
Leave loose
Almost everything else, restaurants, markets, palaces, hikes and neighbourhood wandering, can be handled on the day for less, so resist the urge to over-schedule. Korea is a country best met with a loose plan and a good appetite. One practical test: if cancelling would cost you money, book it; if you could swap it for a better idea over breakfast, do not.
What does a trip to Korea actually cost?
Korea surprises people by being cheaper on the ground than the flights suggest. Getting there and accommodation are the two big lines, and both spike in cherry blossom and autumn foliage season. Everything else is modest: transport is remarkably cheap for the quality, a bowl of noodles or a market dinner costs very little, and a great many palaces, parks, temples and mountain trails are free or nearly so.
Where the money goes if you are not careful: cafes, which are lovely and add up; barbecue and fried chicken nights, which are worth it; and taxis taken out of tiredness when the metro would have done. None of these will ruin a budget, and the season you choose will move it far more than any of them. Prices change, so confirm anything that matters, such as rail fares or flights, on the official or booking site close to your dates.
Money, food and small courtesies
Cash, cards and tipping
The currency is the Korean won (KRW). The rate has shifted substantially in recent years, so check a converter shortly before you travel rather than working from a figure in an older guide. Korea is largely cashless: cards work almost everywhere, and a T-money card covers transport and convenience stores. Still, carry a little cash for traditional markets and small eateries. Tipping is not customary and can even confuse; good service is simply included.
Eating well
Korean food is one of the great reasons to come, so arrive hungry. Meals are social and shared, side dishes called banchan arrive free and refillable, and the barbecue, stews and street food are the stuff of the trip. Some barbecue restaurants are set up for groups, so solo travellers should look for places that welcome one diner. Our food guide covers the dishes and the ordering so you arrive knowing what to ask for.
Table manners
Use two hands when giving or receiving something from an elder, do not stick your chopsticks upright in rice, and pour drinks for others rather than yourself.
Culture, courtesy and getting it slightly wrong
Korea is easy to travel and mildly formal in ways that are worth knowing, and a small effort is warmly received. Age shapes politeness: two hands to give or receive anything from someone older, and let them start eating first at a shared table. On the subway, priority seats stay empty even when the carriage is packed, and taking one is a genuine faux pas rather than a technicality.
Public behaviour is quieter than in many Western cities: people do not eat on the metro, phone calls on public transport are kept short, and raised voices are rare. If you stay in a hanok or a guesthouse with floor seating, expect to take your shoes off at the door. None of this is a test, and nobody expects a visitor to get it all right. Learning annyeonghaseyo for hello and kamsahamnida for thank you covers most situations and lands well.
Staying safe, healthy and connected
Korea is one of the safest countries you can travel in, with very low levels of street crime, and the practical concerns are logistical rather than personal. Data is the one thing to sort in advance, because so much here runs on apps: maps, taxis, translation and ticketing. An eSIM arranged before you fly means all of it works from the airport train onward.
Two health notes. Summer heat and humidity are more demanding than the temperature suggests, so plan indoor breaks. And pharmacies are excellent and widespread for minor problems, with hospitals in the cities well equipped and used to foreign patients. Korean healthcare is excellent and is not free for visitors, so insurance matters here; our guide to travel insurance for Korea sets out what a policy needs to say.
Your first 24 hours on the ground
A short routine takes the friction out of arrival, whatever time you land.
- Get connected: switch on your eSIM or collect your pocket wifi before you leave the terminal.
- Open your map app and save your hotel’s address in Korean as well as English, so you can show it to a taxi driver.
- Buy and top up a T-money card at a convenience store or station machine.
- Check in, drop your bags and walk a few streets rather than starting a long sightseeing day.
- Eat something local nearby and go to bed at a sensible hour, since the first morning goes better for it.
The mistakes first-timers make
Four, and all four are avoidable at the planning stage.
- Assuming Google Maps will work, which it does not fully, and losing a day to it. Fix: install a Korean map app before you fly.
- Leaving the K-ETA question until late, when the waiver list is specific and approval is not instant. Fix: check your passport on the official portal when you book flights.
- Booking five stops in ten days, when the trains being fast is not a reason to keep using them. Fix: cap yourself at three bases.
- Treating Seoul as a stopover, when three or four days is the honest minimum for a city this size. Fix: give it the first block of your trip.
The short version
Start in Seoul, then add Busan by bullet train or Jeju by short flight rather than trying to see everything. Go in spring or autumn if you can, book your peak-season rooms and any DMZ tour early, sort your K-ETA (or confirm your nationality is on the current waiver list) and an eSIM before you fly, and get a T-money card the moment you land. Come hungry, carry a few polite phrases, and leave your evenings loose for the barbecue dinners and market wanders you did not plan. Do that, and your first Korean trip will feel less like a logistics puzzle and more like the start of a habit of coming back.
