Shiwei Mountain Trail. Shiwei Mountain is located on the easternmost side of Dongyin Island, and is one of the highest points on the island with the most expansive views. Shiwei Mountain is located on the easternmost side of Dongyin Island, offering one of the island's most expansive panoramic viewpoints. The trail winds along the sea cliffs, reaching a maximum height of approximately 150 meters, providing a commanding view of the wave-battered coastal erosion formations and the magnificent seascape. Extending from the lighthouse area to geological features like Lie Nu Yi Keng and Yi Xian Tian (One Line Sky), this is the best route to experience Dongyin Island's unique "sea and sky in one line, cliffs facing the sea" topography. Along the way, the vertical joints in the rock walls are clearly visible, forming rare sea cave landscapes shaped by years of sea erosion and weathering. It is a classic trail where nature, geology, and military culture intertwine. Address: 連江縣東引鄉連江縣東引鄉（可於東引遊客中心與燈塔區步道口進入） Hours: 00:00–23:59 Matsu
