Sai Kung, often dubbed Hong Kong’s “back garden,” is renowned for its pristine beaches and hiking trails, but its volcanic rock formations are a lesser-known treasure that captivate geology enthusiasts and adventurers alike. Formed over 140 million years ago during the Jurassic period, these hexagonal basalt columns, particularly at Sai Kung Volcanic Rock Park, showcase nature’s artistry. Experts from the Hong Kong Geopark, a UNESCO-recognized site, explain that these structures resulted from rapid lava cooling, creating striking patterns akin to Northern Ireland’s Giant’s Causeway. This geological marvel offers a tangible link to Earth’s ancient past, blending education with awe-inspiring beauty.
Visiting these formations provides a firsthand experience that’s both humbling and exhilarating. As someone who’s trekked to High Island Reservoir East Dam, where the rocks are most prominent, I can attest to their surreal presence—jagged pillars rising from the sea like a natural fortress. Local guides with decades of experience recommend timing visits for low tide to fully appreciate the exposed columns. The journey involves a ferry from Sai Kung town to Sai Kung Geo Trail, followed by a moderate hike, making it accessible yet rewarding. It’s a perfect blend of physical challenge and geological wonder.
For travelers seeking an offbeat Hong Kong adventure, Sai Kung’s volcanic rocks are a must-see. Trusted sources like the Hong Kong Tourism Board highlight their significance within the Geopark, which spans 150 square kilometers. Unlike the urban bustle of Kowloon or Victoria Peak, this destination offers tranquility and a chance to connect with nature’s raw power. Whether you’re a casual explorer or a geology buff, these formations deliver a unique narrative of time, earning their place as a hidden gem in Hong Kong’s diverse landscape.
