The Itinerary: From Land to Sea

Stop 1: Sai Kung Promenade and Seafood Street
The tour begins with a quick visit to Sai Kung’s lively promenade and famed seafood street. Here, the guide offers a brief introduction to the High Island Supervolcano, erupted 140 million years ago. Understanding the geological importance of this site adds depth to your subsequent views, making the sights more meaningful.

The guide’s commentary here deepens your appreciation for the massive volcanic activity that shaped the region, which last erupted over 140 million years ago. This part is mainly visual, but it plants the seeds of understanding the landscape’s origins.

Stop 3: Po Pin Chau
One of the highlights is the hexagonal basalt columns at Po Pin Chau, often called the “Organ Cliff” due to its organ-like appearance. You’ll be on the boat, looking up at this dramatic cliff face, which is a staggering example of natural geometry. Reviewers describe this as a “musical instrument-like” formation that’s both awe-inspiring and photogenic, especially under bright sunlight.

Stop 4: Wang Chau
Here, you’ll see the Wang Chau Kok Cave, a stunning 30-meter-high sea arch nicknamed “Little Taiwan” because of its shape resembling Taiwan’s map. The boat gets close enough for a good look, and if conditions allow, you might even get a chance to peer inside the arch. Travelers have appreciated the close-up view and the chance to take memorable photos—a favorite part for many.

Stop 5: Basalt Island and Guan Gong Cave
Venture to Basalt Island, home to Guan Gong Cave, the largest sea arch in Hong Kong and East China Seas.

Next is Bluff Island, where you’ll see a sea tunnel and a sea cave—an unusual formation that adds to the geological intrigue. The cave is about 25 meters above the shoreline and 30 meters long.
