Travel Checklist for South Korea from Singapore: Everything You Need Before You Fly

Seoul and Beyond: Why South Korea Deserves Proper Preparation

South Korea has become one of the most sought-after destinations for Singapore travellers over the past few years, driven by a love of Korean food, K-pop, K-drama, and a travel experience that combines cutting-edge cities with deeply rooted traditional culture. Seoul is consistently rated one of the best cities in Asia for food, shopping, beauty products, and nightlife. Busan offers a slower coastal alternative, and Jeju Island delivers volcanic landscapes unlike anything else in the region.

South Korea is not the most spontaneous destination for Singapore travellers. There are entry requirements to check, apps to download, and a few cultural norms worth understanding before you arrive. This checklist covers everything you need to sort before your South Korea trip from Singapore.

Entry Requirements

Check K-ETA Requirements

Singapore citizens can enter South Korea visa-free for up to 90 days for tourism. However, you may be required to obtain a K-ETA (Korea Electronic Travel Authorisation) before arrival depending on current policy at the time of your travel. K-ETA has been waived for Singapore citizens at various points, but the policy can change. Always check the official Korea Tourism Organisation or Korean Embassy website before your trip to confirm whether K-ETA is currently required.

Passport Validity

Your Singapore passport must be valid for the duration of your stay in South Korea. Most immigration guidelines recommend at least six months validity beyond your travel dates to avoid any issues. Check your passport well in advance of your travel date.

Airport Options

Most international flights from Singapore to Korea arrive at Incheon International Airport (ICN), which serves Seoul and is consistently rated one of the best airports in the world. Some budget carriers may use Gimpo Airport (GMP), which is closer to central Seoul but handles fewer international routes.

Getting Around South Korea

T-Money Card

The T-Money card is a rechargeable transit card that works on Seoul's subway, buses, and even taxis across most of South Korea. It also works at convenience stores like GS25, CU, and 7-Eleven. Pick one up at the airport on arrival or at any convenience store. Top it up at subway station machines or convenience stores. It works exactly like Singapore's EZ-Link card.

Seoul Metro

Seoul's metro system is one of the best in the world. It is extensive, punctual, affordable, and fully signposted in English. Download the Naver Maps or Kakao Maps app for navigation as they are more accurate for Korean transit than Google Maps. You will use the metro constantly during your Seoul stay.

KTX for Intercity Travel

The KTX high-speed rail connects Seoul to Busan in about two and a half hours, and to other major cities like Gyeongju, Daegu, and Gwangju. Book KTX tickets in advance through the Korail website or app, especially for weekend travel. Seats fill up quickly during Korean public holidays.

Kakao Taxi

KakaoTaxi is the Korean equivalent of Grab and is the most reliable way to book taxis in South Korea. Download it before you fly and register with your phone number. You need a data connection to use it, which is another reason to sort your Korea eSIM before departure.

Money in South Korea

Korean Won

South Korea uses the Korean Won (KRW). Card payments are very widely accepted in Seoul, including at most restaurants, cafes, convenience stores, and tourist sites. However, some traditional markets, smaller local eateries, and rural areas may be cash only. It is sensible to carry KRW 50,000 to KRW 100,000 in cash at all times.

Withdraw KRW from Korean ATMs

Global ATMs at Incheon Airport, inside 7-Eleven, GS25 convenience stores, and at Woori and Shinhan bank branches accept foreign cards. Withdraw KRW on arrival or at a convenience store. Exchange rates at Korean ATMs are generally good.

Connectivity: Essential for South Korea Travel

Get a South Korea eSIM Before You Fly

Navigating South Korea without data is significantly harder than in other countries. The transit apps, restaurant discovery tools, and translation services you will rely on all require a live data connection. Naver Maps alone is reason enough to sort your data before landing.

Steady eSIM South Korea plans start from just $4.99, which is far cheaper than roaming with your Singapore carrier. Buy your plan at steadyesim.com, install the QR code at home before you fly, and land at Incheon already connected. Your Singapore number stays active for calls and texts while Steady eSIM handles all your data.

Apps to Download Before You Fly

• Naver Maps: essential for Korean transit and navigation
• KakaoTaxi: for booking taxis across Korea
• Papago: Korean translation app developed in Korea, often more accurate than Google Translate for Korean
• Coupang Eats or Baemin: Korean food delivery apps if you want delivery to your accommodation
• Google Maps: download offline Seoul and Busan maps as a backup

Culture and Etiquette

Queue Culture

Koreans take queuing seriously. At subway stations, bus stops, and anywhere with a crowd, look for marked queue lines and follow them. Cutting in is considered very rude.

Removing Shoes

Some traditional Korean restaurants, guesthouses (hansik), and temple areas require you to remove your shoes before entering. Wear clean socks and be prepared to slip them off.

Rubbish Bins Are Rare

Public rubbish bins in South Korea are famously scarce. Carry a small bag for your rubbish and dispose of it at convenience stores or your accommodation. Do not leave rubbish on the street.

Tipping

Tipping is not customary in South Korea and can occasionally cause confusion. A small gesture of appreciation at a traditional restaurant is fine but never expected. Service charges are not typically added to bills.

Shopping in South Korea

Duty Free at Incheon

Incheon Airport has excellent duty-free shopping. Pre-order from Korean duty-free websites like Lotte Duty Free or Shinsegae Duty Free before you fly and collect on departure for significant savings on skincare, cosmetics, and fashion.

Must-Visit Shopping Areas

• Myeongdong: skincare, cosmetics, street food, and fashion
• Dongdaemun: fashion wholesale and late-night shopping
• Insadong: traditional crafts, tea houses, and souvenirs
• Hongdae: indie fashion, streetwear, and youth culture
• Gangnam: premium shopping and beauty clinics

What to Pack for South Korea

• Layers and a warm jacket (South Korea has distinct seasons and even spring and autumn evenings can be cool)
• Comfortable walking shoes (Seoul involves a lot of walking)
• A compact tote bag for shopping
• Portable power bank
• Type C and Type F plug adaptor (South Korea uses 220V Type C/F outlets)
• Your Steady eSIM already installed on your phone
• T-Money card if you have one from a previous South Korea trip
