I'm not sure about this; on paper it sounds great however the playground is not well used and hard to manage as the area is used constantly with people walking their dogs and letting them run wild. There is dog poo everywhere including inside the small childrens climbing area. It never seems to be managed or cleaned.
I've often been there alone with my child when some of these people have arrived with their pit bulls and its not been a comfortable experience. I hope any plans include a sound management strategy as somehow I feel all this investment will be otherwise wasted. Personally I think a play area for younger children should somehow be incorporated into the Horniman Gardens to obtain some critical mass of attendance and to make management easier. The Triangle should remain a local dog walking area and the Horniman Gardens made a dog free zone. In the meantime its still Dulwich Park for us.
