Most tourists from Western countries can enter South Korea visa-free for up to 90 days. However, it's essential to check the specific requirements for your nationality before traveling. Some visitors may need to obtain a visa in advance or register through the Korea Electronic Travel Authorization (K-ETA) system. Always ensure your passport is valid for at least six months beyond your planned stay.

Spring (April to June) and autumn (September to November) are generally considered the best times to visit South Korea. During these seasons, you can enjoy mild temperatures, beautiful cherry blossoms in spring, and colorful foliage in autumn. Summer (July to August) can be hot and humid with occasional monsoon rains, while winter (December to February) is cold but offers opportunities for winter sports and festivals.

South Korea is generally a very safe country for tourists. Crime rates are low, and violent crimes against foreigners are rare. However, as with any travel destination, it's important to exercise common sense precautions such as being aware of your surroundings, safeguarding your belongings, and avoiding walking alone in unfamiliar areas late at night. It's also advisable to stay informed about any current events or tensions with North Korea, although these rarely affect daily life or tourism in South Korea.

South Korea has an extensive and efficient public transportation system, especially in major cities like Seoul. The subway system is easy to use, with signs and announcements in English. Buses are also widely available, and you can use a T-money card for convenient payment on both subway and buses. For intercity travel, high-speed KTX trains offer a comfortable and quick option. Most transportation systems have English language options, and many locals are willing to help if you're confused.

Korean cuisine offers a wide variety of delicious dishes. Some must-try options include bibimbap (mixed rice bowl with vegetables and meat), kimchi (fermented vegetables, usually cabbage), bulgogi (marinated grilled beef), samgyeopsal (grilled pork belly), and Korean barbecue. For street food, try tteokbokki (spicy rice cakes), odeng (fish cakes), and hotteok (sweet pancakes). Don't forget to experience a traditional Korean meal with multiple side dishes (banchan) and try soju, Korea's popular alcoholic beverage.
