Namsan Tower

From the highest point, Seoul Tower has been embracing the city for the last 25 years giving memories and stories to people. In 2005, Seoul Tower was reopened as N Seoul Tower. Many citizens and foreign tourists have visited the Tower and were taken by the scenic view of the city while also enjoying the nature of Namsan mountain. Seoul Tower is located on the peak of Namsan in Seoul, a city of 10 million people. Owing to the tower’s unique structure, the observatory section offers versatile views as the seasons change the appearance of Namsan. Adding to the colourful scenery of the mountain, N Seoul Tower was renovated in 2005 with newly designed high-tech multi media. N Seoul Tower now provides a new cultural space in the center of the city.

Insadong

Insa-dong is the ideal place for visitors who want to experience the true character of Korean art, with its subtle, enduring beauty. Once you are in Insa-dong, you will immediately be drawn to the small alleys lined with numerous shops and galleries, both tiny and spacious: antique shops, Korean stationery stores, frame shops, handicraft shops, pottery and porcelain shops, bookstores and painting studios, and art supply stores. In addition, restaurants and cafes serve traditional food and teas.
During her visit to Korea in 1999, and to Insa-dong in particular, Britain's Queen Elizabeth II expressed deep admiration for the hanbok, Korea's traditional dress, and for Korean pottery in particular. The Insa-dong Festival, held every October, showcases pungmulnori, or folk musical instrumental performances, and features a food court serving local cuisine from regions all across the country. Recently, a shuttle bus service linking galleries in different parts of Seoul has started running between Insa-dong and Pyeongchang-dong.

Hangang Pleasure Boats

In 1986 ferry cruises were started along the sinuous waterway of Hangang River, which flows through the heart of Seoul from the east to the west. Currently there are four ferry terminals, six cruise boats, and 10 motorboats, all offering leisurely excursions. The ferry terminals are located by the riverside at Yeouido, Jamsil, Ttukseom, and Yangwha. Each terminal has a lounge below the deck. The sightseeing boats can be reserved for special occasions including parties, ceremonies, recitals, meeting and seminars.
The blazing glow of the setting sun, the sparkling night scenery of Seoul, the cool breeze on the deck on hot midsummer days, or snowy rides on winter days, all have a romantic ambiance.
