If you’re planning a trip to South Korea, get ready for one of those destinations that feels exciting immediately. Seoul alone has palaces, street food, skincare shopping, cozy cafes, beautiful malls, historic neighborhoods, and some of the easiest public transportation once you get the hang of the apps.

After spending time in Seoul and Incheon, I left feeling like I had only scratched the surface. This guide covers the big-picture things to know before visiting South Korea, including when to go, entry requirements, where to visit, transportation, what to eat, packing tips, money, tax refunds, and a few cultural etiquette notes that will make your trip feel smoother.

Everything You Need to Know for Planning a Trip to South Korea

When is the Best Time to Visit South Korea?

The best time to visit South Korea is usually spring (April to June) or fall (September to November), when the weather is more comfortable, and the scenery is especially pretty. That said, every season has its own trade-offs, so your ideal timing depends on whether you care more about flowers, foliage, festivals, shopping, or avoiding the most intense weather.

Best Times of Year to Visit

• Spring (April to June): April is cherry blossom season in South Korea, and the milder temperatures make it a great time for palaces, neighborhoods, parks, and outdoor exploring.
• Fall (September to November): Fall brings colorful foliage, cooler weather, and a more comfortable setup for long city days or hiking.

Considerations for Weather and Festivals

• Weather: Summers (July to August) can be hot, humid, and rainy, while winters (December to February) can be cold with occasional snow. Check the forecast before you pack because South Korea has four very real seasons.
• Festivals: South Korea has festivals year-round, from lantern festivals to cherry blossoms, fall foliage events, and music festivals. If a festival is a major reason for your trip, verify the current dates before booking flights.

Preparing for Your Trip to South Korea

Visa Requirements and Entry Regulations

• Visa-free entry: U.S. travelers can currently visit South Korea without a visa for up to 90 days for tourism or business. Other travelers should check the latest rules for their passport before booking.
• K-ETA: The K-ETA exemption for U.S. passport holders is currently extended through December 31, 2026. Starting January 1, 2027, U.S. travelers are expected to need a K-ETA before traveling to South Korea.
• Passport validity: U.S. passports must be valid at the time of entry. I would still make sure yours is valid well beyond your travel dates, just for peace of mind.
• e-Arrival Card: South Korea also has an official e-Arrival Card that can be completed online before arrival. Entry rules can change, so check this again close to your trip.
• Prescription medications: If you travel with prescription medication, double-check South Korea’s rules before packing it. Some medications that are legal in the U.S. may be restricted or require approval before arrival.

For the most current U.S. traveler guidance, check the State Department’s South Korea page before you go.

Travel Insurance

• Why it matters: Travel insurance can help with unexpected situations like medical emergencies, trip interruptions, cancellations, and lost luggage.
• Compare plans: Use a quote tool to compare pricing and coverage for your specific trip, especially if you have prepaid flights, hotels, or tours.

Booking Your Flight to South Korea

Major Airports in South Korea

These are not the only airports in South Korea, but they are the main ones most travelers are likely to use when planning a trip.

• Incheon International Airport (ICN): This is the main international gateway near Seoul and the airport most first-time visitors will probably fly into.
• Gimpo International Airport (GMP): Also near Seoul, Gimpo handles domestic flights and some regional international routes, so it can be useful if you are connecting within Korea or nearby countries.
• Other airports: Busan’s Gimhae International Airport (PUS) and Jeju International Airport (CJU) are major hubs if you are adding Busan or Jeju Island to your trip.

Tips for Finding the Best Flight Deals

• Book in advance: Flights are often cheaper when booked a few months ahead, especially if you are traveling during spring, fall, or around holidays.
• Flexible dates: Use Google Flights to compare dates and nearby airports. Even shifting by a day or two can make a difference.
• Layovers vs. direct flights: Direct flights are easier, but layovers can be much cheaper. Just make sure your connection time is realistic, especially on the way there.
• Track the flight: Track fares with Google Flights or sign up for Going well in advance. That link gets you 20% off, and it is one of my favorite travel hacks because they email you when flight sales pop up.

Top Places to Visit in South Korea

Choosing where to go in South Korea can be tough because there is so much variety. You can build a trip around Seoul’s neighborhoods and palaces, Busan’s beaches and seafood, Jeju Island’s nature, Gyeongju’s history, or a mix of city and coastal time.

Must-Visit Places

Seoul

What to expect: Seoul is where I would start, especially for a first trip. It is modern, historic, stylish, busy, easy to shop in, and full of amazing food. You can wander palaces in the morning and end the day at a sky observatory or a massive mall.

Some of the best things to do in Seoul:

• Gyeongbokgung Palace: The most popular of Seoul’s five palaces and a perfect place to pair with a hanbok rental.
• Bukchon Hanok Village: A beautiful neighborhood filled with traditional Korean houses. It is photogenic, but also residential, so be respectful while exploring.
• N Seoul Tower: An iconic viewpoint with panoramic views of Seoul, especially pretty around sunset and at night.

Busan

What to expect: Busan is a great add-on if you want a coastal city with beaches, seafood markets, colorful neighborhoods, and a more laid-back feel than Seoul.

Some of the best things to do in Busan:

• Haeundae Beach: One of South Korea’s most famous beaches, offering a lively atmosphere, beautiful scenery, and plenty of activities.
• Gamcheon Culture Village: A colorful hillside village with artistic murals, galleries, and cafes.
• Jagalchi Fish Market: The largest seafood market in Korea, where you can try fresh seafood and experience the local culture.

Jeju Island

What to expect: Jeju Island is best for nature, waterfalls, volcanic landscapes, beaches, and a slower pace. It is a great choice if you want to balance city time with outdoor exploring.

Some of the best things to do on Jeju Island:

• Hallasan Mountain: The highest mountain in South Korea, offering hiking trails with breathtaking views.
• Seongsan Ilchulbong (Sunrise Peak): A volcanic crater providing stunning sunrise views and a short, rewarding hike.
• Jeju Loveland: A quirky outdoor sculpture park with adult-themed art, so this one depends on your travel style.

Booking Tips and Recommendations

• Book early: Popular areas and accommodations can fill up quickly, especially during peak seasons. Book in advance to secure the best rates and options. Use this tool to see availability and pricing for your dates.
• Read reviews: Check reviews on sites like TripAdvisor and Booking.com to ensure the accommodation meets your expectations.
• Location: Choose accommodations near public transportation, especially in Seoul. Being close to a subway station makes a huge difference when you are out exploring all day.

Transportation in South Korea

Overview of Public Transportation

• Subway: Major cities like Seoul and Busan have extensive subway systems. They are clean, efficient, and usually have signs in both Korean and English.
• Buses: Local buses are an affordable way to get around cities and towns, while intercity buses connect different regions.
• Taxis: Taxis were much cheaper than I expected compared to the U.S. Download Kakao T for easier hailing, and have your destination ready in Korean or pulled up on a map.
• KTX (Korea Train Express): High-speed trains connect major cities like Seoul, Busan, and Daegu. They are fast, reliable, and comfortable.

How to Get a T-money Card and Use It

• T-money card: A rechargeable transportation card used for subways, buses, taxis, and purchases at some convenience stores. You can usually buy and reload one at convenience stores like 7-Eleven or at subway stations. The card itself typically costs around KRW 3,000-5,000, depending on the type or design.
• Using your T-money: Tap your card when entering and exiting the subway or bus. It saves time and makes public transportation feel much less intimidating.

Navigating the KTX

• Buying tickets: You can purchase tickets online or at stations. Book ahead for popular routes, weekends, holidays, or if you need a specific departure time.
• Seating: KTX trains offer reserved seating. Ensure you have your ticket and seat number ready.

Apps to Use for Navigation

• KakaoMap: Helpful for navigation because Google Maps and Apple Maps are not as reliable in South Korea for transit and walking directions.
• Naver Map: This is the one we used the most. I am not going to lie, it made me miss Google Maps so bad at first, but it did get the job done.
• Papago: Download this for translation. It is especially helpful for menus, signs, and quick conversations.

Tips for Using Public Transportation

• Etiquette: Be mindful of others by keeping noise low and leaving priority seats open for the elderly, pregnant women, and people with disabilities.
• Payment: Use a T-money card for convenience, and keep a little cash on hand for reloading or smaller purchases.
• Language: Subway and bus signs are often in both Korean and English, making navigation easier for tourists.
• Be prepared: Whenever you hail a taxi, have the location pulled up before you get in. This makes the interaction smoother if there is a language barrier.

Food and Dining

Korean Foods to Try

• Bibimbap: A mixed rice dish with vegetables, beef, a fried egg, and spicy gochujang sauce.
• Kimchi: Fermented vegetables, usually cabbage, seasoned with chili, garlic, and other spices. It shows up constantly as a side dish.
• Korean BBQ: A social dining experience where you grill your own meat at the table. Try samgyeopsal (pork belly) or galbi (beef short ribs).
• Bulgogi: Sweet-savory marinated beef or pork that is grilled or stir-fried.
• Tteokbokki: Chewy rice cakes cooked in a spicy-sweet gochujang sauce, often with fish cakes.
• Kimbap: Rice and fillings like vegetables, egg, and meat rolled in seaweed. It is great for a quick bite.
• Banchan: Not one dish, but the small side dishes served with Korean meals. These can include kimchi, pickled vegetables, seasoned seaweed, and more.
• Japchae: Stir-fried glass noodles with vegetables and beef, seasoned with soy sauce and sesame oil.
• Hotteok: Sweet pancakes filled with brown sugar, honey, and nuts. Perfect if you want a street food treat.

Dining Etiquette

• Sharing food: Meals are often shared family-style, with dishes placed in the center of the table.
• Using chopsticks: Metal chopsticks are common. Avoid sticking chopsticks upright in rice, as it resembles a funeral ritual.
• Tipping: Tipping is not expected in South Korea. Just pay the bill as shown unless a service charge is already included.

Packing Tips for South Korea

One of the best South Korea travel tips I can give you is to pack light and save room for shopping. You can buy many things locally, including clothes, Korean skincare, makeup, toiletries, and convenience store basics.

Many hotels also provide shampoo, conditioner, body wash, toothbrushes, and toothpaste, so this is a great place to use my space-saving packing hacks.

Essentials to Pack

• Travel adapter: South Korea uses Type C and Type F power outlets with a standard voltage of 220V. If you bring hair tools, make sure they are dual-voltage.
• Comfortable shoes: Expect to do a lot of walking, especially in Seoul. These are my go-to travel shoes, and comfort matters more than you think when your day includes palaces, subway stairs, shopping, and cafes.
• Weather-appropriate clothing: Check the forecast and pack accordingly. Layers are key for spring and fall, breathable outfits help in summer, and winter requires real cold-weather pieces.

My full South Korea packing list breaks down exactly what I packed, what I skipped, and what I would bring again.

Cultural Etiquette and Customs

Public Behavior

• Quiet in public: Keep your volume low in public places like subways and buses. Public transportation felt much quieter than what I am used to in the U.S.
• Personal space: Be mindful of personal space and avoid unnecessary physical contact with people you do not know well.
• Bowing: A slight bow or nod is a simple way to show respect in everyday interactions.

Dress Code

• Modesty: Dress respectfully when visiting temples, palaces, and cultural sites. You do not need to overthink it, but avoid anything that feels too revealing for a historic or sacred space.
• Shoes: Remove your shoes when entering someone’s home or certain traditional spaces. Many hotel rooms also provide slippers.

Additional Tips for Planning a Trip to South Korea

Communication Tips

• Be patient: Communication can sometimes be challenging, but patience and a positive attitude go a long way.
• Learn a few phrases: Even knowing simple words like hello, thank you, and excuse me can make interactions feel warmer.
• Use Papago: Papago is especially helpful for Korean translation. I would also keep Google Translate downloaded as a backup.

Currency and Payments

• Currency: The currency in South Korea is the Korean won (KRW). If you have an iPhone, your calculator actually has a feature where you can convert currency.
• ATMs: ATMs are easy to find, especially in convenience stores like 7-Eleven. Look for international ATMs that accept foreign cards.
• Credit cards: Credit cards are widely accepted in urban areas, but I would still carry some cash for markets, street food, and smaller shops. Bring a card with no foreign transaction fees if you have one.

Staying Connected

• Wi-Fi: Free Wi-Fi is common in hotels, cafes, and some public places, but I would not rely on it for everything.
• eSIMs: I recommend setting up an eSIM before you land so you can use maps, translation, rideshare, and messaging without hunting for Wi-Fi after a long flight.

Tips for Bargaining

• Markets: Bargaining may be possible in markets like Namdaemun and Dongdaemun, but keep it polite and read the situation.
• Cash: Having cash on hand can make market shopping easier, even if you use cards most of the trip.

Tax Refunds for Tourists

• Eligibility: Non-Korean citizens staying in Korea for less than six months may be eligible for tax refunds on qualifying purchases.
• Procedure: Look for stores displaying Tax Refund or Tax Free signs. The current minimum purchase amount is 15,000 won per receipt, and the items must be new, unopened, unused, and taken out of Korea within three months. Present your passport when shopping and keep your receipts. Read more about the procedure here.
