It is the highlight of the trip which can be seen only on the Daeijakdo Island.
It is a sand island, also called "pulchi", which shows its appearance only at low tide.
A sand island appears for about six hours a day, and when the water comes out, it disappears in a flash.
You can step on the beach only when you go in time.
The whole shape of Puldeung Beach can be seen from the summit of Buasan Mountain.
