Cai Pu Ao Introduction
The Coastal Erosion Wonders of Caipu Bay is located at the base of Jianguo Road, northeast of Xiju Island, under Tianwo Village. The coastal natural landscape is characterized by typical granite cone shapes, with long, slender horizontal joint patterns of granite radiating into the sea. Due to the erosion caused by seawater, various cliffs and dangerous reefs have formed, creating layers of waves, resulting in a highly diverse coastal terrain. The unique coastal erosion landscape is the main geographical feature of the Caipu Bay Geopark. Before the completion of the Qingfan Deep Water Port, Caipu Bay was the primary summer port of entry and exit for Xiju. During the summer, south winds and waves can reach level 7 or higher, requiring passenger and cargo ships to dock at Caipu Bay. Additionally, due to the large changes in surrounding sea currents and the abundance of fish, it serves as an excellent spot for sea fishing and shell collecting. Caipu Bay is also known for its abundant laver, and during the harvest season, a large rock belonging to the Chen General Temple along the coast is opened for bidding, with the winning bidder gaining the right to collect laver from the rock. This is considered a unique local custom in Matsu. Currently, the outer area of Caipu Bay is open for visitors to explore, but there is still a military presence; visitors can experience the hardships and joys of being stationed at the cape by following the instructions provided. Observing the Blue Tears at the Matsu Xiju War Ruins, the former observation platform at Caipu Bay, free from light pollution, serves as the best spot for photographing the blue tears at night. From the platform, one can gaze down and witness the blue tears sparkling with blue light as the waves crash against the rocky shore, appearing beautiful in the sea. Note: Due to the absence of surrounding lights at night, along with it still being a military site and strong sea winds, it is recommended to be guided by a local tour guide when going to see the blue tears and to pay attention to personal safety.
