Essential Travel Tips
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.
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.
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.
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.
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.
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.
