More than 40 km south of Tuy Hoa city, Phu Yen province, the Cliff of Stone Plates looks, from a far distance, like a huge beehive which is about 50 meters in width, 200 meters in length. The cliff is structured with a set of prismatic stone pillars placed adjacently. The vertical pillars and inclined ones standing in close position adjoining to the sea resemble big plates that are supernaturally placed. The cliff is the result of ancient volcanic eruptions when the molten basalt flows hardened and formed these spectacular polygonal pillars. In 1998, the Cliff of Stone Plates was recognized as a national landscape.
