RE: A beach where you are undisturbed, a really hidden beach.

For me this is a special place. When all beaches and my dive center were closed due to Corona in Phuket, I went for a lot of walks and discovered some such places because you can only reach them on foot.
And in addition to swimming, snorkeling was not possible because of the poor visibility, this place was also a perfect place not to have to see the blocked paradise. (And I really had some wonderful hours there. But that doesn't belong here.)
