a children's recreation area that never gets boring to visit.. lots of green trees make it good for healing without having to go far from Jakarta.. clean, only visitors who come are ungrateful, some throw rubbish anywhere, smoke as they please, clearly in a public place, lots of small children, toddlers and elderly people are very disturbing/air pollution.. people like this are more precisely people who have no brains and low human resources.. hopefully Ancol can make a firmer policy regarding smoking rules, especially in certain spots. thanks
