The bow cuts through teal water and salt spray carries the volcanic scent of old fire—this is Sai Kung from the low angle that reveals its carved cliffs and sea arches. On this two‑hour speedboat tour you skim past the thousand hexagonal columns of High Island, thread narrow straits when conditions allow, and circle massive sea arches that the surf has hollowed into natural gateways.

The bow cuts through teal water and salt spray carries the volcanic scent of old fire—this is Sai Kung from the low angle that reveals its carved cliffs and sea arches. On this two‑hour speedboat tour you skim past the thousand hexagonal columns of High Island, thread narrow straits when conditions allow, and circle massive sea arches that the surf has hollowed into natural gateways.
These basalt columns are the visible remnants of a supervolcanic eruption roughly 140 million years ago; ash and lava cooled into the distinctive hexagonal joints you now see lining two kilometers of coast. Local fishermen and boatmen have used the same channels for generations, and place names around Basalt Island and Po Pin Chau reflect a maritime culture shaped by tides, rocks and typhoons.
Expect short on‑shore stops at a Volcano Discovery Centre followed by 90 minutes offshore among the Ung Kong Group, Jin Island, Bluff Island and the Guan Gong and Wang Chau Kok arches. Terrain is boat deck and glassy sea; geology is the main attraction. Wildlife is mostly seabirds and occasional porpoises.
Practically: wear non‑slip shoes and sun protection, bring a waterproof phone case, and be prepared to move to the bow for photo moments. Tours are weather‑dependent—rough seas may prevent arch transits. The trip is suitable for most fitness levels but not recommended for those with serious back or heart conditions or for late pregnancy. If you want close views of basalt columns and dramatic sea arches in a compact, photo‑packed outing, this speedboat run delivers.
Boatmen may attempt to navigate through some arches when wave and tide conditions are safe; this is always weather‑dependent and not guaranteed.
Yes—infants must sit on an adult’s lap; children should be supervised on deck and wear life jackets provided by the operator.
The trip includes a guided visit to the Volcano Discovery Centre, a guided speedboat route around Ung Kong Group, life jackets and a tour guide who provides geology and history commentary.
Full refunds are available if you cancel at least 24 hours before departure; the operator will cancel for bad weather and low passenger counts.
