Hong Kong can be very busy.
But still, surrounded by wonderful nature you will definitely find a place to relaxe. One of them is Stanley Beach. It takes about an hour to go there, with the MTR to Central or Admiralty and then the bus 6, 6x or 6A (not 100% sure about that) to Stanley Beach. There you can do shopping at the waterfront market or just relaxe, rent a boat or do a windsurfing course.
I got the impression that there are many Western people – that did not bother me though, it only made the prices at the waterfront restaurants a bit more expensive. But the view is so nice, there is an amazing place that sells Frozen Joghurt and you can just breath and forget the buzz of the city.
