Health and Safety
Seoul is among the safest cities in the world. Some areas are less safe but most of the city is fine at all times of the day.
Health-wise, medical attention is very expensive in Seoul so it is advisable to make sure you don’t fall sick or get into some medical problem there. If you are already on medication, make sure to carry enough medicines with you to last your trip. As the local food there contains high amounts of black pepper and ginger, it is advisable to be careful when eating Korean dishes.
