I. Documents Required for Visa Application

All visa-free travelers shall prepare their passport, return ticket and accommodation bookings for inspection.

II. Transportation Options
Urban Transportation
Rail transit is the primary travel mode in core cities such as Seoul and Busan. Subway lines cover business districts, scenic spots and transport hubs with convenient transfers, making them the top choice for avoiding road congestion.
Bus routes cover extensive areas, reaching neighborhoods and attractions not served by rail transit, serving as an important supplement to urban travel.
The T-money transit card is recommended. It is valid for subways, buses, taxis and other forms of public transport, and can also be used for small-value payments at convenience stores and vending machines. It is easy to recharge and accepted in most cities nationwide.
Taxis can be hailed on the street, and ride-hailing apps are available in some cities, making them suitable for trips with heavy luggage or short journeys with time constraints. Public transport coverage on Jeju Island is limited, so chartered cars or self-driving rentals are common travel options.

Intercity Transportation
The KTX (Korea Train Express) connects major cities across the country with frequent services and high punctuality, serving as an efficient option for long-distance intercity travel.
Long-distance buses have extensive routes with regular seats and sleeper services, reaching most small and medium-sized towns and suitable for slow-paced travel.
The domestic flight network is well-developed, with frequent flights between Seoul, Jeju, Busan, Daegu and other cities, ideal for long-distance cross-regional travel.
General Transportation Etiquette
Stand on the right side of escalators, keeping the left lane clear for fast passage.
Keep voices low on subways and buses, set mobile phones to silent mode, and avoid loud conversations or phone calls.
Follow the "alight first, board later" rule, queue in an orderly manner, do not rush for seats, and offer seats to the elderly, pregnant women and people with reduced mobility.
III. Weather and Dressing Guide
Spring (March–May): Temperatures rise gradually with significant day-night temperature differences. March remains cool, while May is warm and pleasant, with mostly sunny weather during the cherry blossom season. Layered dressing is recommended: thin long-sleeve tops as inner layers, paired with a windbreaker, light coat or knit cardigan. A thin scarf can be useful for cool mornings and evenings.
Summer (June–August): The rainy season mostly falls in June, while July and August are hot and humid, with occasional typhoons around the turn of summer and autumn. Wear breathable, quick-drying short sleeves and shorts, and carry a dual-purpose umbrella and sun protection products. Indoor air conditioning is strong, so a thin cardigan is advisable for temperature differences.
Autumn (September–November): The weather is cool and dry, making it a comfortable travel season with stunning fall foliage scenery. Day-night temperature differences gradually widen as autumn progresses. Wear long-sleeve inner tops paired with a light windbreaker or casual coat, and switch to a thicker coat for late autumn to adapt to temperature changes.
Winter (December–February): The climate is cold and dry, with snowfall in most regions and even lower temperatures in northern mountainous areas. Wear a thick down jacket, warm sweater, thermal underwear and non-slip, warm footwear. Warm accessories such as hats, scarves and gloves are recommended. Jeju Island, influenced by its maritime climate, has relatively mild winters and does not require extremely heavy cold-weather gear.

IV. Payment Methods
Bank cards: Credit cards are extremely widely used in South Korea. International credit cards such as Visa and MasterCard are accepted at the vast majority of shopping malls, restaurants, hotels and convenience stores. UnionPay cards can be used directly at major business districts, duty-free shops, chain brand stores and convenience stores in core tourist cities including Seoul, Busan and Jeju.
Cash: Traditional markets, street food stalls, small restaurants, some rural scenic spots and short-distance transport still mainly accept cash. It is advisable to carry a moderate amount of South Korean won in cash, preferably in small denominations for daily use.
Mobile payment: Alipay and WeChat Pay are widely accepted at large shopping malls, duty-free shops, chain convenience stores, popular scenic spots and catering outlets in tourist-dense areas, allowing direct QR code payment. Coverage is limited in smaller towns and local merchants, so it is not recommended as the primary payment method.
Additional tips: Transit cards such as T-money support small-value payments at convenience stores and vending machines. ATMs at bank branches and chain convenience stores generally support cash withdrawal with overseas bank cards for on-demand cash top-ups.
