The Shengsi Islands are part of the Zhoushan Archipelago and lie off the mouth of the Yangtze in Zhejiang province; the group comprises 394 islands of which only about 18 are inhabited. The largest island is Sijiao Island, and the islands are administered as Shengsi County under Zhoushan City.
The islands have a subtropical maritime climate and support a busy seasonal fishery that brings large numbers of fishermen in winter. Many of the smaller islets are rocky or covered with scrub; inhabited islands have small fishing villages, working harbors and simple visitor facilities.
Visiting is typically about island-hopping by ferry or charter boat, sampling seafood and exploring coastal walking routes and village lanes; services can be limited on quieter islands, so plan logistics and accommodation in advance.
- Sijiao Island: The archipelago’s largest island, offering the widest range of services, beaches and boat connections to other islets.
- Fishing villages: Small harbors and village streets give a direct look at traditional fishing life and local seafood culture.
- Island-hopping boat trips: Short ferries and private charters link islands and provide coastal views, rocky headlands and beach stops.
- Gouqi and nearby islets: Gouqi is one of the better-known inhabited islands used as a base for exploring the cluster.
- Photogenic abandoned spots: Some ruins and overgrown coastal villages attract photographers, especially at low tide and in soft light.
