i visited on June'16 when the temperature is high. not so convenient because i sweat a lot and tired. you better to choose another time when the weather is more friendly.overall , the place is very nice for your whole family.one more, don't plan to go back to city by taxi. apparently, not so many taxi come by. you better take MTR. If you depart from airport and go as a group, better to take taxi as it cost only HKD125, cheaper than taking MTR
