Essential Travel Tips

transport

Get a T-Money card immediately upon arrival. You can buy and top it up at convenience stores (like CU or GS25) and use it for subways, buses, and even taxis. It's way more convenient than buying single tickets and often gives you a small discount on transfers.

food

Don't be afraid to eat at 'sikdang' (small, local eateries) – they often have the most authentic and affordable Korean food. Look for places packed with locals, point at what looks good on the menu (even if you don't read Korean), and prepare for a delicious, no-frills meal.

culture

Learn a few basic Korean phrases like 'Annyeonghaseyo' (hello) and 'Kamsahamnida' (thank you). While many people in tourist areas speak some English, making an effort with the local language is greatly appreciated and can enhance your interactions.

money

While credit cards are widely accepted, always carry some cash for smaller vendors, street food stalls, and traditional markets like Gwangjang Market. ATMs are readily available, but inform your bank about your travel dates to avoid card issues.

packing

Pack comfortable walking shoes – you'll be doing a lot of exploring on foot, whether it's through bustling markets or historical palaces. Also, consider bringing a portable Wi-Fi egg or getting a local SIM card; reliable internet is essential for navigation and communication.

safety

Seoul is incredibly safe, but it's still wise to be aware of your surroundings, especially in crowded nightlife areas like Hongdae or Itaewon. Keep your valuables secure, and if you're out late, know the number for emergency services (119).

💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

GoWithGuide Tours and Experiences

Getting Around Seoul, South Korea

Seoul Metro

The Seoul Metro is an extensive and efficient subway system that covers most of the city and its surrounding areas. It's the backbone of public transportation, connecting major attractions, business districts, and residential neighborhoods.

Cost:Base fare starts at ₩1,250 (approx. $1 USD) with additional charges based on distance. A T-Money card is highly recommended for convenience and discounts.
Tip:Download the 'Kakao Metro' or 'Seoul Metro' app for real-time navigation and train arrival times. Always tap your T-Money card at both the entry and exit gates. Avoid rush hours (7-9 AM and 5-7 PM) if possible, as trains can get extremely crowded. Offer your seat to the elderly, pregnant women, or those with disabilities – it's a strong cultural norm.

Intercity Buses

Seoul's intercity bus network is vast, connecting the capital to virtually every corner of South Korea. They are a cost-effective way to travel to cities and regions not directly served by the KTX high-speed train.

Cost:Varies greatly depending on the distance, but generally much cheaper than the KTX. A trip from Seoul to Busan can range from ₩25,000 to ₩45,000 (approx. $20-$35 USD).
Tip:Book tickets in advance, especially for popular routes or during holidays, via apps like 'Bustago' or 'Kobus'. Arrive at the bus terminal at least 15-20 minutes before departure. Most terminals have clear signage in English, but having the Korean name of your destination handy is always a good idea.

Kakao T (Taxi App)

Kakao T is the dominant ride-hailing app in South Korea, offering standard taxis, premium 'Kakao Black', and even designated driver services. It's incredibly convenient for door-to-door service, especially late at night or when carrying luggage.

Cost:Metered fares apply, similar to traditional taxis, with surcharges for late-night travel. Expect to pay around ₩4,000-₩5,000 (approx. $3-$4 USD) for short rides within the city.
Tip:Download the 'Kakao T' app and link your credit card or set up a payment method. While many drivers speak basic English, it's helpful to have your destination written in Korean or displayed on your phone. Don't try to hail taxis directly on the street during peak hours; use the app for better availability.

Airport Railroad Express (AREX)

The AREX provides a direct and efficient link between Incheon International Airport (ICN) and Gimpo International Airport (GMP) to Seoul Station. It's the fastest way to get from the airport to the city center.

Cost:The Express train (non-stop to Seoul Station) costs ₩9,500 (approx. $7.50 USD). The All-Stop train makes several stops and is slightly cheaper.
Tip:Purchase tickets at the airport station or via the official AREX website/app. If you have a T-Money card, you can use it on the All-Stop train but not the Express train. The Express train is ideal if you're staying near Seoul Station; otherwise, the All-Stop train connects to the Seoul Metro system.

Bicycle Sharing (Ttareungi)

Seoul's public bicycle sharing system, 'Ttareungi', is a fantastic way to explore parks, riverside paths, and certain neighborhoods at your own pace. It's especially pleasant during spring and autumn.

Cost:A 1-hour rental costs ₩1,000 (approx. $0.80 USD), with additional hours costing more. A 24-hour pass is available for ₩5,000 (approx. $4 USD).
Tip:Download the 'Ttareungi' app and register with your phone number and credit card. You'll need to unlock bikes using the app. Stick to designated bike lanes and paths; riding on sidewalks is generally discouraged and can be dangerous. Always lock the bike properly at a designated station to avoid extra charges.
