1. 하늘공원 억새축제
from Oct. 18-24, there will be a silver grass festival at Sky Park(하늘공원) near World Cup Stadium Station.

i think the most important thing is to see the sunset.
if you don't have to watch the festival lights at night, it doesn't matter if you go before the festival period.

* 마니마니 stairs.
it's a park built on a landfill site, so it's on a hill.
if you don't want to walk up to the park entrance, take an electric car.
there's a ticket office near the parking lot of the World Cup Stadium.

* it may not be fun.
there's nothing but silver grass.
pink muhly grass are famous. that's all.
in fact, IG photo zone. yuriasLaugh 

* take the subway.
destination is Exit 1 or  2 of World Cup Stadium Station on Line 6.

2.경의선 숲길 (Gyeongui Line Forest Road)

here is the place where the railroad tracks have been turned into a forest(?) road.
name is forest road, but there's actually about 6km long grass road.
if you walk one block to Sogang Bridge side, you will see it.
you walk to near Hongdae, you will see many stores and restaurants. (too many famous places. 연남동 커피냅로스터스, 제주맥주, etc...)

it's perfect to go to Plan B.
it's close to both, so it'll be fine to go tomorrow right away.
copy Korean and search it before you go.

p.s 

고양 가을꽃축제 (Goyang Autumn Flower Festival)

the lake park is a little far away, but tomorrow is the last day of the festival.
It will be perfect to take a walk in the lake park in autumn weather.
