Lake in Hong Kong

Don't know why I haven't been here all these years. DisneyPark draws water from this man made lake for irrigation and best of all this opens to the public for free. There is a nice round the lake walk of about 2k+, I saw a few running there that day. If your family isn't that heavy you could rent a paddling boat or a 4-wheeler cycle. Parking is very limited, I doubt if public transport is available there.
