Where is this Mabul Island?
When the water tide is really low, one can walk from the beach aaall the way to the edge where the water is much, much deeper. But you don't want to go that far out as the fun is just near the island. See the line where the water is darker? Just don't exceed that border if you wish to just walk ok.
Mabul is a looong way from Kuala Lumpur.
