Cai Pu Ao Introduction
Xiju Coastal Erosion Marvels is located at the end of Jianguo Road in Cai Pu Ao on the northeastern side of Xiju Island, which belongs to Tianwo Village. The coastal natural landscape is characterized by typical granite conical formations. The granite veins display elongated horizontal banding that radiates into the sea, which has been eroded by seawater, creating cliffs and reefs of varying sizes and building up layers of waves. This results in a highly diverse coastal terrain, and the unique coastal erosion landscape is the most prominent geographical feature of Cai Pu Ao Geopark. Before the completion of the Qingfan Deep Water Dock, Cai Pu Ao was the main summer harbor for entering and exiting Xiju. During the summer, south winds can whip up waves reaching 7 degrees, requiring passenger and cargo ships to dock at Cai Pu Ao. Additionally, the surrounding waters have significant current variations and abundant fish resources, making it an excellent spot for sea fishing and shell collecting. Furthermore, due to the abundant production of nori (seaweed), it has become locally known. During the harvest season, a large rock near the Chen Jiangjun Temple along the coastline is opened for bidding, and only the winning bidder is allowed to collect the nori from the rock, representing a unique local custom in Matsu. Currently, the area around Cai Pu Ao has been opened for travelers to visit, but it remains a military outpost. Visitors can experience the joys and challenges of guarding this coastal area by following the given instructions. Viewing Blue Tears in the Remnants of War in Matsu's Xiju: The former observation platform at Cai Pu Ao, free from light pollution, serves as one of the best spots for photographing blue tears at night. Looking down from the platform, blue tears sparkle with blue light as the waves crash against the rocky shore, creating a beautiful sight. Note: The surroundings are dark at night, and due to the continued status as a military outpost and strong sea winds, it is advisable to have a local tour guide familiar with the area to safely observe the blue tears and ensure personal safety.
