I was there during first week of November, it was still very pink and "fluffy". Not sure about December though. It was already Winter in December.

The park would be the most beautiful during fall (around late october will be the most beautiful). June would be a little bit too hot cause you have to climb up lots of ladder to reach the park, so it will be kind of exhausting. But if you're okay with hot weather then it will be okay.

Hi! I agree with LeowD1. After the long escalator from Exit 1, just turn left or if you are bit confused, just used Google Maps or Naver Maps. A little bit of walking around 8 to 10 minutes. I think you will not get lost because it has signages. Below it, they have the shuttle bus, you just have to line and ask if it will be shuttle bus going to Haneul Park. I think walking going to Haneul Park is worth to try. We walk to Haneul Park just to experienced what Koreans always do.

I can’t confirm but I don’t think the Eulalia plants will be available anymore in late Dec due to the extremely cold weather. But still good to check with those who went to the park now / this week.

Hi! It is still visible and available. These type of grass also lives in a cold season/winter season. Enjoy Korea!

Take blue l;ine 4 subway from Myeongdong to Sangakji. Transfer to brown line 6 to Mapo-gu Office station or World Cup Stadium Station. It's walking distance from either.

Not really. Especially this year, we have a delayed and extended summer. Most likely a moth later.
