South Korea offers excellent public transportation, high safety standards, and advanced digital infrastructure. However, entry procedures, daily customs, and cultural practices differ significantly from other countries. This guide covers what first-time visitors need to know to avoid unnecessary confusion.
1. K-ETA Requirements: Check Your Status
Current Status (December 2025): Travelers from 67 visa-exempt countries do not need K-ETA through December 31, 2025. Starting January 1, 2026, K-ETA will be required again for these countries.
When K-ETA is Required (from Jan 1, 2026):
-
- Apply at least 72 hours before departure
-
- Cost: 10,000 KRW (approximately $7-9 USD)
-
- Valid for 3 years for multiple entries
-
- Approval is verified before boarding your flight
-
- Ensure passport information is accurate—errors can delay approval
Important: Even during the exemption period, you can voluntarily apply for K-ETA to skip filling out the arrival card at Korean immigration.
2. Public Transportation System
Seoul and major cities have extensive subway and bus networks with English signage. The system is efficient, affordable, and relatively easy to navigate.
Key Points:
-
- T-money card: Rechargeable transit card that works on buses, subways, and some taxis nationwide. Available at convenience stores and subway stations.
-
- Priority seating: Designated seats for pregnant women, elderly, and people with disabilities should remain empty unless you qualify. This rule is strictly observed.
-
- Quiet culture: Keep phone conversations brief and speak quietly. Loud talking is considered disruptive.
-
- Late-night service: Most subway lines stop around midnight. Night buses operate after subway hours.
3. Navigation Apps: Google Maps Has Limitations
Google Maps does not provide walking or driving directions in Korea due to government restrictions on exporting detailed map data for national security reasons. For reliable navigation, use Korean map applications.
Recommended Apps:
-
- Naver Map: Most comprehensive option with English, Japanese, and Chinese interfaces. Provides real-time public transit information, walking directions, and business details.
-
- KakaoMap: English interface available. Strong restaurant and cafe database with user photos and reviews.
Usage Tip: Search for locations in English on Google to find the Korean name, then copy and paste into Naver Map or KakaoMap for accurate results.
4. Payment Methods: Cards Dominant, But Cash Still Needed
Korea has extremely high card usage rates. Contactless payment is widely accepted, and most establishments accept major international credit cards (Visa, Mastercard).
Where Cash is Required:
-
- Traditional markets
-
- Small street food vendors
-
- Rural areas and small villages
Recommendation: Carry 50,000-100,000 KRW (~$35-70 USD) in small denominations. ATMs are widely available at convenience stores, banks, and subway stations.
5. Tipping: Not Expected or Required
Korea does not have a tipping culture. Service charges are included in prices at restaurants, hotels, taxis, and cafes. However, if you insist on tipping as a sign of gratitude, it will be appreciated.
6. Internet Access: Mobile Data vs. Wi-Fi
Free Wi-Fi is available in cafes, subways, shopping centers, and many public spaces. However, consistent mobile data access is more practical for navigation, translation, and ride-hailing services.
Options:
-
- SIM cards: Available at airport convenience stores and telecom shops. Prepaid plans typically range from 30,000-50,000 KRW for 5-10GB over 30 days.
-
- eSIM: Can be purchased and activated before departure. Convenient for compatible devices.
-
- Pocket Wi-Fi rental: Suitable for groups traveling together. Available at airports with daily or weekly rates.
7. Safety and Security
Korea has one of the lowest crime rates globally, with a homicide rate of approximately 0.5-0.6 per 100,000 residents—about one-tenth of the global average. Walking at night in urban areas is generally safe.
Basic Precautions:
-
- Secure valuables in crowded tourist areas
-
- Remain aware of surroundings, especially late at night
-
- Don’t leave bags unattended, even in perceived safe locations
-
- Petty theft, while uncommon, does occur in busy districts
8. Electrical Standards
Specifications:
-
- Voltage: 220V
-
- Frequency: 60Hz
-
- Plug Types: Type C (round two-pin) and Type F (round two-pin with side grounding clips)
What You Need:
-
- From 110V countries (US, Canada, Japan): Adapter required. Check if devices support dual voltage (100-240V). Most phone chargers and laptops do; hair styling tools often don’t.
-
- From Europe (except UK): Usually compatible without adapter
-
- From UK, Australia, Singapore: Adapter required
Recommendation: Universal adapters with USB ports allow you to charge multiple devices simultaneously.
9. Language Considerations
English proficiency varies significantly by location and generation. Major tourist areas, hotels, and airports have English-speaking staff. Outside these areas, English support becomes limited.
Helpful Tools:
-
- Papago: Naver’s translation app, often more accurate for Korean than Google Translate
-
- Google Translate: Works for basic communication
-
- Learn basic phrases: Simple greetings and “thank you” (감사합니다, gamsahamnida) are appreciated
Translation apps with camera functions are particularly useful for reading menus and signs.
10. Cultural Customs to Observe
- Shoes: Remove shoes when entering homes, some traditional restaurants, and temple buildings. Look for shoes at the entrance as an indicator.
- Bowing: A slight nod or bow is a common greeting. Deep bows are reserved for formal situations.
- Two hands: When giving or receiving items (especially from elders or in business settings), use both hands or support your right arm with your left hand. This shows respect.
- Dining: Wait for the eldest person to begin eating. Don’t stick chopsticks upright in rice—this resembles funeral rituals.
11. Seasonal Considerations
-
- Spring (March-May): Mild weather, cherry blossoms. Popular travel season.
-
- Summer (June-August): Hot and humid. Monsoon season typically late June through July brings heavy rainfall.
-
- Fall (September-November): Cool, dry weather. Excellent for outdoor activities.
-
- Winter (December-February): Cold and dry. Good for winter sports. Temperatures often drop below freezing.
Korea’s infrastructure is genuinely excellent once you understand how it works. The combination of efficient public transit, advanced mobile payment systems, and high safety standards makes it one of the most traveler-friendly countries. The key is knowing which tools to use and which cultural norms to observe.

Korea is accessible, safe, and well-organized. With basic preparation and cultural awareness, first-time visitors can navigate the country confidently.
