“Freshwater Well on the Seaside” on Koh Nui, a small island in front of Koh Tha Rai, Pak Ao Taled of Khanom Sea, is a footprint-shaped rock well with water flowing all the time. During the high tide, the seawater will flood over the pond while during a dry season, the well with freshwater appears. The villagers in this area believe that this is the footprint Luang Pu Thuad showing his supernatural power by stepping on the seawater to change it into freshwater. This is a phenomenon that corresponds to the folk since ancient times.
