Gyeongui Line Forest Park, located in Seoul's Mapo District, is a beautifully transformed urban park that stretches along the former Gyeongui railway tracks. With its lush greenery, walking trails, and unique blend of nature and history, the park offers a peaceful retreat for visitors to relax, unwind, and enjoy recreational activities amidst the bustling cityscape.

I recommend walking from Gongdeok Station all the way to Hongdae and stop for a good coffee every now and then.
