Best places to visit in South Korea

Seoul

Allow at least four days for Seoul’s royal palaces, traditional neighbourhoods, markets, museums, contemporary districts and nearby hiking. The metro is extensive, but journey planning and map apps are valuable when moving between neighbourhoods.

Busan

Busan combines beaches, seafood markets, temples, hillside neighbourhoods and coastal viewpoints. Two or three nights provides a useful contrast to Seoul.

Jeju Island

Jeju is best for volcanic landscapes, waterfalls, coastlines and hiking. A rental car can improve flexibility, while mobile data helps with route planning and weather-dependent activities.

Gyeongju

Gyeongju adds royal-era heritage, temples and archaeological sites. It works well between Seoul and Busan or as a focused cultural side trip.

Jeonju

Jeonju is known for hanok architecture, regional food and a slower travel pace. It can be included as an overnight stop or paired with other central destinations.

Sokcho and Seoraksan

Sokcho is a practical base for Seoraksan National Park and the northeast coast. Conditions can change quickly in mountain areas, so check current forecasts and trail information.

Spend four nights in Seoul and three in Busan, travelling by high-speed rail. This is the simplest first-time route.

10 days: Seoul, Gyeongju and Busan

Add one or two nights in Gyeongju between the two major cities for a stronger heritage component.

Best time to visit South Korea

Spring

Spring is popular for mild sightseeing weather, parks and seasonal blossoms. Demand can be high around major bloom periods, so reserve transport and accommodation early.

Summer

Summer is hot, humid and often rainy. It can suit coastal and festival travel, but build flexibility into outdoor plans and carry rain protection.

Autumn

Autumn is one of the strongest seasons for cities, hiking and multi-region trips. Comfortable weather and fall colour make mountain destinations especially appealing.

Winter

Winter is cold and dry in many areas, with opportunities for skiing, seasonal food and quieter city sightseeing. Pack for low temperatures and shorter daylight.

Getting around South Korea

High-speed rail links major cities, intercity buses extend regional coverage and metro systems are efficient in large urban areas. Domestic flights are useful for Jeju. Keep key addresses saved in Korean where possible and use mobile data for current transit routes, translation, restaurant queues and reservations.

How much mobile data do you need in South Korea?

• 3–5 GB: messaging, occasional maps and light browsing
• 5–10 GB: regular navigation, translation, transit apps and social media
• 10–20 GB: frequent uploads, video calls, multi-city travel and heavier daily use
• Unlimited data: hotspot use, streaming, remote work or travellers who prefer not to track usage

For a South Korea-only trip, compare the South Korea fixed-data eSIM and South Korea unlimited plan. For other supported destinations, consider the Asia 20 areas eSIM or Asia unlimited data plan.

Power, payments and practical tips

South Korea commonly uses Type C and F sockets with 220 V and 60 Hz electricity. Verify charger compatibility before travelling. Cards are widely useful, but a payment backup is sensible. Install your eSIM before departure, save setup information offline and keep your original SIM available when needed for banking or verification messages.
