Why are the woods so busy tonight?

Was looking at places to go for a walk tomorrow and noticed Sydenham Hill Woods is much “busier than usual” right now according to Google Maps. The thing is it’s 3° outside and 8.30pm at night.

I’ve been there many times before and it’s lovely but definitely not the kind of place I’d want to be wandering around in the dark - Blair Witch vibes.

Does anyone have a logical explanation? Google Maps glitch? Dogging hotspot?
