Yanxiu Chaoyin is one of Dongyin's Eight Scenic Spots, located on the sea cliffs on the island's northern side. When waves surge through rock fissures into a natural wind cave, compressed air produces a deep tidal booming sound that rises and falls in rhythm with the waves. The clifftop commands open views, and the nearby sea cliffs are an important breeding site for black-tailed gulls (Larus crassirostris). During specific seasons each year, you can observe gulls nesting in the cliff walls — a spot on Dongyin that combines both soundscape and birdwatching.
Highlights of Yanxiu Chaoyin
The name "Yanxiu Chaoyin" draws on two images: yan (swallow/seabird), referring to the seabirds that nest here; and chaoyin (tidal sound), referring to the resonant sound produced when waves surge into the rock-fissure wind cave. The cliff landform on Dongyin's northern side is complex; the granite's well-developed joints have been eroded by waves over time, forming multiple natural wind caves. The shape and depth of a cave determine the timbre of its tidal sound: in heavy seas it booms like a drum; in calm conditions there is only a low airflow hum — each visit offers a different experience.
Black-tailed gulls nest in the cliff walls of Dongyin, and during the breeding season you can observe adult birds feeding chicks. When the flock is in flight, wingspans can exceed one meter — an impressive sight wheeling above the clifftop. The clifftop here also overlooks the northern sea around Dongyin Island, a good position for watching sea surface activity and looking out toward the Chinese mainland. Bringing binoculars will greatly enhance the birdwatching experience.
