Pratas Islands

Island Taiwan-administered coral atolls with strategic reef ecosystem

The Pratas (Dongsha) Islands are Taiwanese‑administered coral atolls in the South China Sea; access is restricted, but the area is noted for diving, reef ecology and a maritime nature reserve.

The Pratas Islands, also known as Dongsha, are an atoll and group of reefs in the northern South China Sea administered by Taiwan’s Kaohsiung City. The feature includes a single larger cay with supporting facilities and an enclosed lagoon ringed by coral reefs.

The atoll is protected for its marine biodiversity and reef systems and has been designated as a national park and marine reserve. The environment comprises shallow lagoon habitat, reef flats and deeper slopes that support coral assemblages and reef fishes.

The islands are administered by Taiwan and are visited only with authorisation; a small garrison and park staff maintain presence on the main cay. The atoll lies in the northern South China Sea, several hundred kilometres southwest of Taiwan’s main island.

Administration and access: Administered by Taiwan (Kaohsiung City) and designated a marine national park, access is restricted and typically requires permits from Taiwanese authorities.
