Sea Dragon Gate is located on the northeast side of Dongyin Island, a unique sea cave landscape sculpted by years of coastal erosion. The massive rock has been carved by waves into a magnificent arch shape, resembling a dragon's head raised and its body low to the ground when viewed from afar, hence the name "Sea Dragon Gate." As the tide rises and falls, seawater passes through the rock arch, and waves crash against the cave walls, creating a majestic and spectacular natural wonder. It is one of the most visually striking coastal erosion landscapes in Dongyin. Address: 連江縣東引鄉連江縣東引鄉（位於東引島北側沿海區域，依觀景點與步道指標即可抵達） Hours: 00:00–23:59 Matsu
