If you want to get out of the city but don’t want to travel to long then this is the best option! Bukhansan is one of the best mountains to go hiking. It’s located behind the President’s pad, Cheongwadae or Blue House. The mountain offers different trails and takes you through reconstructed 15th century gates and the ancient fortress wall. From the top, which is definitely doable, but wear good shoes, you have an amazing view of Seoul. This mountain is definitely worth a visit if you feel like getting out of the concrete jungle that is Seoul.
