Though it is relatively a "touristic" spot since it is promoted by Hong Kong Tourism Board, not too…read moremany people really did try to hike here before guess because of its steepness vs Dragon Back (a real touristic spot. Now it is as crowded as mongkok after being promoted. So pretty sad to me)
So, I think Ng Tung Chai still kept its original nature, and really recommend you to go if you love HK natural side!
Another reason I recommend you a go is that it is really hard to believe how gorgeous the waterfall is until you reach there! I browsed web photos and thought it is small, but when I reach there, I was totally amazed!
Tips: Go earlier around 8/9am so that you will not meet crowd just in case :)
Tips 2: Definitely it cannot be compared with waterfall in other countries LOL but if to compare within HK, it is the tallest, longest and would say best!
