Sizihyu’s “Zao Long” is a unique, open-top sea erosion cave in Penghu. A set of popular online photos shows how seawater has flowed through basalt columns over thousands of years, carving out the cave. Viewed from above, it looks like a blue pearl on the island. Bathed in sunlight, the crystal-clear waters reveal the basalt reflecting the blue hues, a marvel of nature that creates this spectacular blue cave landscape.

Its sudden fame has led to a constant stream of tourist boats visiting. However, as “Zao Long” is an actively eroding geological formation, navigating boats into it is extremely dangerous. Improper handling can cause rock collapses, and there have even been reports of near-disasters when visitors ventured in recklessly.

The Penghu County Government has invoked the “Cultural Heritage Preservation Act” to impose fines. Areas including Sizihyu’s Zao Long and the surrounding connected sea zones fall within the “Penghu South Sea Basalt Nature Reserve.” Any unauthorized boats or tourists entering this area are considered to be illegally landing on the island, with penalties of up to five years in prison and/or fines of up to NT$1 million.
