South Penghu Marine National Park

Island in Outer Penghu Islands

Comprises a series of small but beautiful islets and sea stacks between Wang'an and Chimei, plus over 35,000 hectares of surrounding waters. The four biggest islands have remnant villages, though they're largely uninhabited these days other than fishermen's shacks and occasionally used temples.

Visits are only possible by tours, which usually stick to diving on the fine reefs and visiting the ocean basalt formations rather than landing on the islands.
