Seoul is multi-faceted and has something for all visitors! One of the best neighbourhoods to tour is Myeongdong, the town centre that's famous for paved streets lined with shops. It's Heaven on Earth! During the evening the shops remain open and street stalls sell delicious, cheap food.
History lovers should head to the neighbourhood of Buckchon. If you get off the metro at Anguk, you'll find yourself in a district full of 'hanoks', the traditional Korean houses. Today, many of them are guest houses, which makes for a great Korean-style stay. A must-do during a trip to South Korea! This part of town is also home to the Royal Palace.
In addition to these two neighbourhoods, it must be said that all of Seoul is worth a visit! Itaewon is the ideal place to party, as it's a melting pot with numerous bars. Gangnam is also worth a tour - a wealthy business district with mind blowing shopping centres and the most beautiful hotels in the city.
Finally, I loved the cable car that takes you up Namsam hill, where you'll get a fantastic view of the city. It's even more impressive at night!
Amongst the things not to miss in the city, you have to visit at least one of the imperial palaces. In Gyeongbokgung, the main old palace, you can see the changing of the guard every hour. Between times, the guards come under attack from tourists armed with selfie sticks.The Changdeokgung Palace is equally impressive.
The temple of Jogyesa, close by to the palace, is particularly beautiful when the anniversary of the Buddha draws near, when it is decorated with hundreds of lanterns.
Then, to discover traditional Korean houses, the hanoks, I headed towards the Bukchon quartier and I got a map at the information centre, so as to discover the different itineraries of the local area.
To go through the traditional market, head towards Yangyeongsi. The shops selling medicinal herbs are very numerous, a window into the inside of the train station will give you an idea of all that can be found.
If you prefer shops, go into the Gangnam quartier, shopping paradise and plastic surgery.
In the evening, I advise you to walk to Cheong-gye-cheon. It's an artificial water course in the middle of which there are illuminated art pieces, but also pedestrian bridges....
If you want to see Seoul from on high, the N Seoul Tower, on the summit of mount Namsan, will suit you perfectly. It's accessible by foot (a good half an hours walk with a lot of stairs) and also by bus. The place is known as the meeting point of lovers, they sell padlocks, photos and other goodies.
