Cimei is the southern outlier of the Penghu islands, small enough to circle by scooter but distinct enough to justify the trip from Magong. The island is dry, low, and basalt-edged, with fishing villages, sea cliffs, and a handful of sights that show how closely Penghu life has always been tied to the water.
The headline stop is the Double-Heart of Stacked Stones, a traditional tidal fish trap shaped like two linked hearts. Nearby, Little Taiwan turns the island's wave-cut basalt into a natural map of Taiwan, while the south coast has the white Qimei Lighthouse and wide sea views.
Cimei is not a resort island. Ferries and flights are limited, shade can be scarce, and most visitors come as a day trip. That works well if you start early, rent wheels, and treat the island as a slow coastal circuit rather than a list of photo stops.
