Tianwei Mountain stands on a coastal headland in Jieshi Town, Lufeng City, Guangdong Province. Nestled between mountains and the sea, it features a wealth of landforms including sea-eroded pillars and grooves, earning it the reputation of an "Underwater Park".

At low tide, a stunning array of uniquely shaped sea-eroded pillars comes into view. You can find sea stone forests, sea mushrooms, stone turtles, sail-shaped rocks, sea immortals, sea dragons and walrus-like stones. Wandering here feels like stepping into a vast open-air sculpture park on the sea. These exotic stone formations make this headland a spectacular scenic tourist attraction.
