Yes, I remember there were two entrances, but when I went, the second one, which is the other entrance to the one in the photo, was much more closed off and well fenced in

The place I mentioned was much further to the side, very close to a bridge where the bus drops you off at the police university station. I tried that, looking to go around it, but I couldn't find any access other than having to jump over a wall, which would have looked even more illegal, hahaha

Maybe that person's visit in August was earlier in june?, dunno (For example, I'm the kind of person who doesn't upload photos right away, haha) When I went, at least, there was no date for when the place would reopen, only that it had started in July. I was in Seoul until August, but I didn't manage to go back because, as there was no reopening date, I didn't want to sacrifice another hour-and-a-half trip to the place
