Met a Chinese family swimming in the river and they asked me where I am from. I told them KL and they asked: "How on earth did you manage to find this place?". They said even though they are locals, they got lost getting here the second time around.
Since it is a weekday, the place is almost deserted. I was told on crowded weekends, it is also visited by locals mostly. Nice that the locals have their own secret and very remote hideout for recreation and picnics. Maybe not (so secret) anymore.
