A Guide to Navigating Korea, One of Asia’s Most Fascinating Destinations

By Oscar Davis

South Korea is a country that rewards curiosity. It’s a place where neon-lit megacities meet quiet mountain temples, where high-speed trains glide past rice paddies, and where centuries-old etiquette still shapes daily life. As the original document puts it, “South Korea is full of wonders,” and for first-time visitors, the key to enjoying those wonders is understanding how the country works.

Whether you’re coming for K-pop pilgrimages in Seoul, hiking Hallasan on Jeju Island, exploring the hanok alleyways of Jeonju, or soaking in the hot springs of Busan, a little preparation goes a long way. This GoNOMAD-style guide blends practical tips with a deeper look at what travelers can expect once they land.

Getting In: Entry Requirements Made Simple

South Korea’s entry system is efficient, but it helps to know what’s required before you arrive. Most travelers will need apply to either a K-ETA (Korea Electronic Travel Authorization) or a visa paired with an e-arrival card. If you’re a visa-free tourist, then you’ll have to apply for the K-ETA, which takes about 72 hours and can be done online. 

The K-ETA is straightforward: apply online, wait up to 72 hours, and you’re cleared to enter. If you don’t qualify for visa-free entry or didn’t apply for the K-ETA, you’ll complete the e-arrival card online within three days of arrival. The uploaded document explains that the new system “allows both visitors and immigration officers to process entries faster,” and that’s true—immigration lines in Seoul’s Incheon Airport move with impressive speed.

Once you’re through, you’ll find one of the most traveler-friendly airports in Asia, complete with showers, lounges, and a high-speed train that gets you into Seoul in under an hour.

Understanding Money: A Cashless Society with a Few Quirks

South Korea is one of the world’s most digitally connected countries, and that extends to payments. Credit cards are widely accepted, but locals overwhelmingly use mobile wallets like Naver Pay and Kakao Pay. Apple Pay and Google Pay exist, but acceptance is inconsistent.

Tourists should carry a small amount of cash for rural areas, traditional markets, and mom-and-pop restaurants. ATMs are easy to find, and currency exchange booths at Incheon offer fair rates.

One uniquely Korean option is the WOWPASS, a prepaid card designed for travelers that doubles as a transit card. It’s especially handy if you want to avoid juggling cash and cards.

Getting Around: One Card, Endless Options

South Korea’s public transportation system is a marvel—clean, punctual, and extensive. As the document notes, “Most of the time, all you need is a single transportation card.”

In Seoul, that card works on subways, buses, taxis, and even the city’s shared bikes. Tmoney is the most common, but EZL, Namane, and the Climate Card for Seoul all work similarly. You tap in, tap out, and recharge at any convenience store.

Travelers should know:

• Cash is rarely accepted on buses, so get a card immediately upon arrival.
• The subway is the fastest way to move around Seoul, especially during rush hour.
• KTX high-speed trains connect Seoul to Busan, Daegu, Gwangju, and beyond, making cross-country travel easy.
• Jeju Island has no subway, but buses are reliable and cheap.

If you’re planning day trips, Korea’s rail network makes places like Suwon Fortress, DMZ tours, and the coastal city of Gangneung easy to reach.

Essential Apps: Your Digital Toolkit

Google Maps doesn’t work well in Korea due to government mapping restrictions. Instead, download:

• Naver Map – the most accurate for walking and transit
• KakaoMap – excellent for driving and bus routes
• Papago – Korea’s best translation app
• Kakao T – the Uber of Korea, used for taxis
• Coupang Eats or Shuttle – food delivery if you’re staying long-term

Additionally, if you will be using an eSIM for South Korea to keep connected, don’t forget to download your carrier’s app to monitor your plan. Then, you will be able to pick what’s more convenient for your trip.

Etiquette: Korea’s Blend of Tradition and Modernity

South Korea is high-tech, but etiquette still matters. The document lists several important basics, including taking your shoes off indoors, greeting with a nod, and giving or receiving items with both hands.

Here are a few more cultural nuances travelers notice:

Dining Culture

• The oldest person at the table begins eating first.
• Pour drinks for others before pouring your own.
• Slurping noodles is fine—encouraged, even.
• Many restaurants specialize in one dish; trust the menu.

Social Norms

• Koreans value harmony and modesty. Loud voices in public transport are frowned upon.
• Personal space is smaller than in the U.S., especially in subways.
• Tipping isn’t expected, but rounding up or leaving small change is appreciated in tourist areas.

Temple Etiquette

• Dress modestly.
• Bow slightly when entering a shrine hall.
• Photography rules vary—always check signs.

Staying Connected: SIM Cards, eSIMs, and Wi-Fi Everywhere

Korea’s 4G and 5G networks are fast and reliable. You can buy a physical SIM at the airport or use an eSIM, which the document calls “a cheaper and more convenient option.”

Public Wi-Fi is abundant in cafés, subways, and hotels, but having your own data plan makes navigation and translation much easier.
