Located off the northern coast of Dongyin Island, Sanlian Islet is composed of three connected small islands, forming a rare offshore islet cluster landscape in the Matsu region. The island's rock formations are heavily eroded by the sea, clearly showcasing sea stacks, sea arches, and layered joints, making it a natural geology classroom. Due to its steep terrain and uninhabited nature, it retains a pristine natural appearance. On clear days, the distinct silhouette of Sanlian Islet makes it an excellent spot for sea viewing, photography, and observing coastal landforms. Address: 連江縣北竿鄉連江縣北竿鄉三連嶼 Hours: 00:00–23:59 Matsu
