Planning your first trip to South Korea? From the modern streets of Seoul to traditional markets, historic palaces, and coastal destinations, Korea offers experiences that can feel both exciting and unfamiliar to first-time visitors.
However, arriving in a new country can also raise practical questions. How do you get from the airport to the city? Will your credit card work? Do you need cash? And what should you know about Korean customs?
This guide covers 15 essential things to know before visiting South Korea in 2026, helping you prepare for a smoother, more comfortable trip.

- Check Your Passport and Entry Requirements
Before booking your flight, check the entry requirements that apply to your nationality.
South Korea's visa requirements depend on your passport, the purpose of your visit, and how long you intend to stay.
Some travelers can enter for short visits without a visa, while others must obtain one in advance.
South Korea also operates the Korea Electronic Travel Authorization (K-ETA) system.
As of October 2026, eligible nationalities benefit from a temporary K-ETA exemption that has been extended through December 31, 2026. However, not every nationality qualifies.
Before departure, confirm your requirements through the official website:
Always check the latest regulations shortly before traveling, as immigration requirements can change.
- Choose the Best Time to Visit Korea
South Korea has four distinct seasons, and each offers a different travel experience.
Spring (March to May)
Spring brings mild temperatures, blooming flowers, and popular cherry blossom destinations. It is an attractive season for walking tours and outdoor activities.
Summer (June to August)
Summer is generally hot and humid, with a rainy period and occasional severe weather. Lightweight clothing and an umbrella are useful.
Autumn (September to November)
Autumn brings cooler temperatures and colorful foliage. It is particularly pleasant for exploring parks, palaces, and mountain trails.
Winter (December to February)
Winter can be very cold, especially in Seoul and inland regions. Snow activities, seasonal festivals, and winter food are popular attractions.
For visitors who prefer comfortable walking weather, spring and autumn are often appealing choices.

- Understand How to Travel from Incheon Airport
Incheon International Airport is a major international gateway to South Korea.
After arriving, you can travel to Seoul by airport train, limousine bus, taxi, or private transfer.
The Airport Railroad Express (AREX) offers convenient train connections.
The express train connects Incheon Airport and Seoul Station, while the all-stop train serves additional stations along the route.
An airport limousine bus may be more convenient if your accommodation is near one of its stops, particularly when traveling with large luggage.
Before choosing transportation, check your hotel's exact address and the nearest station or bus stop.
Official airport information:
Travel tip: A train may be faster for reaching Seoul Station, but the best option depends on where you are staying.
- Get a Transportation Card
A rechargeable transportation card is one of the most useful items for traveling around Korea.
Tmoney cards can be used on many subway and bus services and are widely available at convenience stores.
You can generally purchase one at major convenience store chains such as CU, GS25, and 7-Eleven.
Transportation cards help simplify payments and may provide transfer discounts when switching between eligible public transportation services.
A few useful things to remember:
Keep some Korean won available for card purchase or recharging.
Check your remaining balance before traveling.
Tap your card when entering and, where required, when exiting.
Do not assume a foreign bank card can be tapped directly at every subway gate.
Some transportation passes are designed specifically for short-term visitors to Seoul, so compare the options if you plan to use public transit frequently.
- Download the Right Navigation Apps
Getting around South Korea becomes much easier when you have the right mobile apps.
NAVER Map
Useful for finding public transportation routes, walking directions, and local businesses.
KakaoMap
Another option for local navigation and exploring places in Korea.
Papago
A translation app that can help with Korean menus, signs, and everyday conversations.
k.ride
A taxi-booking service designed to make transportation more accessible to international visitors.
Install essential apps before arriving and test whether they work with your preferred language settings.
For important destinations, save the Korean-language address as well as the English name.
- Prepare Internet Access Before Arrival
Reliable internet access makes traveling in South Korea much easier.
You may need mobile data to check directions, translate menus, confirm reservations, or communicate with accommodation providers.
Common options include:
eSIM
A convenient choice for travelers with compatible smartphones. Some plans can be installed before departure.
Physical SIM card
Available through mobile service providers and selected airport locations.
Portable Wi-Fi
Useful for groups that want to share one internet connection, although the device needs to be carried and charged.
Before buying an eSIM, confirm that your phone is unlocked and compatible with the service.
Compare coverage, data limits, activation instructions, and the length of your trip rather than selecting a plan based only on price.
- Carry Both a Credit Card and Some Cash
Credit and debit cards are widely accepted at many hotels, restaurants, convenience stores, and shopping centers in Korea.
However, international cards do not work in every situation.
Some smaller businesses, transportation card machines, and local services may require a different payment method.
It is sensible to carry a modest amount of Korean won for unexpected situations.
Before your trip:
Check whether your card supports international payments.
Review foreign transaction fees.
Learn how your bank handles currency conversion.
Keep a second payment method available.
If a card terminal offers a choice between your home currency and Korean won, compare the conversion terms before accepting.
- Learn How Korean Restaurants Work
Eating in Korea can be one of the most memorable parts of your trip.
However, restaurant customs may differ from those in your home country.
Some restaurants provide water and side dishes, known as banchan, at no additional charge.
In certain casual restaurants, customers collect their own water, utensils, or side dishes from a self-service area.
At barbecue restaurants, meat may be cooked at the table. Depending on the restaurant, staff may help with the cooking.
Many restaurants provide chopsticks and spoons, and it is common to share several dishes.
Tipping is generally not expected in ordinary Korean restaurants.
Travel tip: If you have food allergies or dietary restrictions, prepare a written explanation in Korean before visiting restaurants.
- Know a Few Useful Korean Phrases
You do not need to speak fluent Korean to enjoy your trip.
However, learning a few simple expressions can make everyday interactions easier.
| Korean | Meaning |
|---|---|
| 안녕하세요 (Annyeonghaseyo) | Hello |
| 감사합니다 (Gamsahamnida) | Thank you |
| 죄송합니다 (Joesonghamnida) | I'm sorry |
| 얼마예요? (Eolmayeyo?) | How much is it? |
| 화장실 어디예요? (Hwajangsil eodiyeyo?) | Where is the restroom? |
| 영어 하세요? (Yeongeo haseyo?) | Do you speak English? |
Korean people may appreciate the effort even if your pronunciation is not perfect.
For more complicated conversations, a translation app can be extremely helpful.
- Understand Basic Korean Etiquette
Korea combines modern lifestyles with traditions that still influence everyday interactions.
Understanding a few customs can help visitors feel more comfortable.
For example, removing shoes is customary when entering many private homes and some traditional accommodations or restaurants.
When giving or receiving something in a formal situation, using both hands can be a polite gesture.
On public transportation, designated priority seats should be left available for eligible passengers.
When visiting temples, palaces, or other culturally significant places, follow the posted rules and respect restricted areas.
You do not need to memorize every custom. Being considerate and observing local behavior is a good starting point.
- Choose Your Accommodation Area Carefully
Where you stay can significantly affect your travel experience.
For a first visit to Seoul, the best area depends on what you want to do.
Myeongdong
Convenient for shopping, sightseeing, and exploring central Seoul.
Hongdae
Known for its youthful atmosphere, cafes, nightlife, and creative shopping areas.
Insadong
A good choice for visitors interested in traditional culture, galleries, and historic neighborhoods.
Gangnam
Offers modern shopping districts, restaurants, hotels, and a different side of city life.
Rather than choosing a hotel solely because of its price, check its walking distance from public transportation.
A slightly more expensive hotel near a convenient station may save time and transportation costs.
- Remember That Korea Uses 220V Electricity
South Korea generally uses 220-volt electricity at 60 Hz.
Common power outlets accept round-pin plugs, usually Type C or Type F.
Visitors from countries with different plug types may need a travel adapter.
Before plugging in a hair dryer, curling iron, or other high-powered appliance, check whether it supports the local voltage.
Many modern phone and laptop chargers support a wide voltage range, but this should always be verified on the device label.
A plug adapter changes the physical connection. It does not necessarily convert the voltage.
- Plan Around Korean Public Holidays
Major public holidays can affect your travel plans.
Two particularly important holidays are Seollal, the Lunar New Year, and Chuseok, often described as Korea's harvest holiday.
During these periods, many people travel to visit their families.
Long-distance transportation may become busy, and some businesses operate on different schedules.
At the same time, visitors may find special cultural events and seasonal activities.
If your trip overlaps with a major holiday, check transportation reservations, opening hours, and attraction schedules in advance.
Do not assume every restaurant, market, or attraction will follow its regular schedule.
- Explore Beyond Seoul
Seoul is a wonderful starting point, but South Korea offers much more.
Busan
A major coastal city known for beaches, seafood, and colorful neighborhoods.
Gyeongju
A historic destination with ancient temples, royal tombs, and cultural landmarks.
Jeju Island
Famous for volcanic landscapes, coastal scenery, and outdoor experiences.
Jeonju
Known for traditional architecture, regional cuisine, and its famous hanok village.
Even a short journey outside Seoul can reveal a different side of Korean culture and daily life.
If you have a week or more, consider adding one destination rather than trying to visit too many places.
- Save Important Emergency and Travel Contacts
Before arriving in Korea, save a few important numbers on your phone.
112 — Police
For situations requiring police assistance.
119 — Fire and ambulance
For emergency medical or fire services.
1330 — Korea Travel Helpline
A tourist information service offering assistance in several languages.
You can also access information through the official Korea Tourism Organization website:
https://english.visitkorea.or.kr/
Keep a copy of your hotel's address, emergency contacts, passport information, and travel insurance details somewhere you can access without mobile internet.
If an emergency occurs, having this information prepared can save valuable time.
