Abney park is a cemetery but also a gay jungle. If you go to the bottom right part of the park, between the small paths there is where the men are. Mostly older men, 30+ (but I am 20 and I go a lot haha). The only issue is that the park closes with the sunset, so from November to March closes quite soon, but from April to October is more doable. Please do not stop cruising here, we need to keep our memory.
