Nui Island - A Freshwater Spring in the Middle of the Sea Nui Island is a small gem nestled in Khanom's waters, renowned for its unique natural phenomenon. When the tide recedes, a freshwater spring resembling a human footprint emerges, only to be submerged again when the tide rises. This spring is steeped in legend, believed to be the source of the story surrounding Luang Pu Toad walking on freshwater. On the island, there's a statue of Luang Pu Toad, where visitors can ascend to pay their respects. At the top, a viewpoint offers breathtaking panoramas of the expansive sea and a stunning array of nearby islands. This island is part of the boat tour experience to observe the captivating pink dolphins and the incredible fabric-like rock formations in the waters of Khanom.
