Yijiangshan Islands

Islands Zhejiang archipelago known for historic naval battles

The Yijiangshan Islands in Zhejiang are known for their 1950s battle history and coastal fortifications; visitors see military relics, lighthouses and shoreline scenery on short island visits.

The Yijiangshan Islands are a small archipelago off the coast of Zhejiang province in eastern China, located in the East China Sea. The islands form part of the coastal island chain of Zhejiang and consist of rocky, low‑lying islets with local fishing activity and coastal scenery.

The islands are primarily of local importance for fisheries and coastal navigation; they do not have large permanent settlements and are accessed from the Zhejiang mainland by small boats. Maritime conditions and tides determine accessibility.

Geographically the group lies off Zhejiang’s shoreline in the East China Sea and is administered as part of the province’s coastal counties.
