hot in recent days, it is better to visit here at night. Buy some cold drinks at the convenience store or cafe at the tower, you can enjoy the nice night view of Seoul with fresh air. Please use bus to get to the top of Namsan mountain.
Very nice view in a clear day or night. We were there at the late after noon and night and it was pretty. You need to ride a cable car or bus to come up or it will be quite hard on foot.
Buildings with a backdrop of mountains and cars look like ants! The views and colors are amazing so you should bring a camera with you. This should be your number one place to visit. I strongly recommend you this place!
