I want to do a picnic, but at night. Will that be possible? Or does the park have a closing time?

It closes, but I don't necessarily think they're in a hurry to kick you out.

Closes at 8 p.m.

Is close by 8 pm

When we were there a police offer was escorting everyone out of the park.

You should be fine. It doesn't close till 8

Yes they do close, but not sur time.
