Autumn arrives at Sky Park, pick up the level, and now is Seoul World Cup Stadium, Sunset Park, Lanzhichuan Park, Peace Park. The higher you climb, the more you can see the beautiful scenery of the Han River, the wide view of Seoul. Who would have imagined the natural beauty in front of them, once a landfill site in Seoul, where a pile of garbage has formed a "garbage mountain" 33 times the size of the Egyptian pyramids because of the low-lying terrain. The landfill was closed until 1993, when it reached its limit and the city government decided to build an ecological park here to show the public how nature is alive and well in the barren land. Autumn is charming, a large golden mango grass waved and waved in the field, and the happiness came so simple. Finally, I understand why this place is called "Sky Park". Because it feels like the sky is within easy reach of you. Especially close, especially blue, especially beautiful.
