Right next to Guosheng Lighthouse(國聖燈塔) is a seafront sandbank which forms the southern border of Qigu Lagoon. Sand from the alluvial deposits of Taiwan's western rivers, carried by the waves of the Taiwan Strait, constantly accumulates and has gradually formed a long and narrow sandbank at sea level. Barren landscapes are rare in Taiwan, and some feel it is equal to the Tottori sand dunes in Japan, while some call it the Taiwanese version of the Sahara Desert(撒哈拉沙漠). At sunset, the sandbank's undulating lines cause many photographers to linger, and because of its tranquility some people bring yoga mats to stretch facing the vast ocean. In recent years, due to the popularity of posting photos on the internet, the sandbank has become a hot spot for many people to take photographs and check-in.
