About Yijiangshan Islands#

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.

How to Get to Yijiangshan Islands#

Access is by local ferry or charter boat from Zhejiang coastal towns; schedules vary seasonally and should be confirmed with local operators.

Tips for Visiting Yijiangshan Islands#

  • Check local notices before planning a visit - some islands in the archipelago have seasonal military or coastguard activity.
  • Use licensed local boat operators for island-hopping; they know safe landings and navigation through shoals and reefs.
  • If planning to snorkel, bring your own gear - services on small islands are limited.
