Path to ‘secret beach’

Was wondering how ‘secret’ a beach can be while displayed on google maps but only a handful of people there so perhaps I should have checked out ‘hidden’ beach while in Hoi An.
It’s a full time job for the cafe/bar owners here clearing the coral from the beach each day. They were at it around 7am while I was exploring and were still at it when I returned about 4pm. To think they have been doing that since 2004 gives you some idea of the scale of the catastrophe.
So yes, another idyllic beach day for me!
