At 78, a doctor from Zhejiang has already travelled the world.
He’s seen famous coastlines, iconic cliffs, and postcard views in many countries.
But when his boat rounded the coast of Sai Kung and the hexagonal volcanic columns came into view, he stopped, looked for a long time, and said:
“Hong Kong is the most beautiful, the most stunning of all.”
These are not just rocks. They are the frozen fingerprint of a supervolcano that erupted around 140 million years ago, cooling slowly into millions of perfectly formed hexagonal columns.
Most hexagonal columns around the world are dark basalt; Hong Kong’s are rare, light-coloured, silica-rich rhyolite, spread over about 100 km² of land and sea, with columns averaging 1.2 m in diameter and some reaching 3 m across.
Standing in front of them, this seasoned traveller realised that what makes Hong Kong special isn’t just its skyline, but this world-class geological wonder hidden along our coastline.
Hong Kong is not only a concrete forest.
We also have a UNESCO Global Geopark, 140-million-year-old volcanic hexagonal columns, wild islands, sea caves, and coastlines that rival any destination he’s visited.
And from the water, with Splitdyboat, you don’t just see them from afar – you glide right up to the walls of rock and feel how small you are next to 100 metres of ancient volcanic pillars.
If a 78-year-old doctor who’s seen the world says Hong Kong is the most stunning, maybe it’s time we all look at our home with new eyes.
