This is the most basic one-day course for tourists visiting Korea. It is also a good idea to move in the order listed below.
Gyeongbokgung Palace
Gyeongbokgung Palace is the royal palace of the Joseon Dynasty located in Jongno-gu, Seoul. It was founded in 1395. It is a must-visit course if you visit Korea as it contains a traditional folk museum.
Compared to other countries, the entrance fee is very cheap(3,000krw /per person). Try wearing hanbok at a hanbok rental shop near the palace. If you visit the palace wearing Hanbok, you can enter for free. Closed every Tuesday.
Bukchon Hanok Village
A Hanok(Korean traditional house) neighborhood located in the north of Seoul, and it was also called ‘noble village’ because most of the luxury houses were where royal family members, noblemen, and government officials lived since the Joseon Dynasty. There are actually residents living here, but they are bothered by the large number of visitors. It is best not to enter the house without permission or make noise.
Insadong
Insadong is traditional/antique street. There are Korean restaurants and cafes all over the place, making it a place worth visiting at least once. Many people promote it as an traditional antique street, but in fact(in my opinion), many antique shops have disappeared and now there are more just commercial souvenir stores. People who expected antiques may be somewhat disappointed.
Kwangjang Market
Visit the traditional market in the center of Seoul and enjoy it together. There’s even a famous Netflix nanny who cooks Korean pancakes, street food, and ‘kalguksu’! This is a Korean local market located in the center of Seoul, mainly focusing on textiles and food. There is a local Korean atmosphere. But as tourist visits increase, disappointments emerge. Please refer to this post.
N Seoul Tower
Take the cable car up Namsan Mountain and enjoy a panoramic view of Seoul. It is one of the famous places where you can enjoy the night view of Seoul. It is also crowded with tourists during peak season evening hours. You can go up to Namsan Mountain by cable car(paid), but in good weather, you can also go up on foot or by bus.
