It is interesting place. I never would imagine something like that in Hong Kong. You take MTR to Yuen Long and walk north. Away, from high rises and civilization. In 10 minutes you will arrive to small wooden pier, which seems like it was there for last hundred years.

This tiny boat will take you across of canal and you walk to place which hard to describe. I will not even try.

Sometimes it is better not to thing ‘why?’ and ‘what is that?’

Just walk and enjoy. BTW, after ferry you will find a small shack where you can get some snack and drinks. Get it because there are no other facilities there.
