Sai Kung Island Hopping: Four Sea Arches & Basalt Columns Day Tour
Spend a day on a speedboat through the Sai Kung Volcanic Rock Region to see sea arches, columnar basalt and sheltered bays. This compact UNESCO Geopark circumnavigation packs geology, coastal caves and a beach snorkel into a single 6-hour outing.
The Experience
Before You Go
Bring reef-safe sunscreen
Apply reef-safe SPF and reapply after swimming to protect marine life and reduce skin damage under strong subtropical sun.
Wear secure water shoes
Rocks are sharp and slippery at landing spots and in caves—closed-toe water shoes improve grip and protect feet.
Be ready for short swims
Some stops include optional swimming or coasteering; if unsure, inform the guide so they adjust plans and provide extra flotation.
Charge your camera and stow valuables
Bring a small dry bag; boats can be wet and phone cameras do best with waterproof protection for cliff and cave shots.
Local Knowledge
Hidden Gems
- •Sea Palace viewpoint at Wang Chau for intimate views of hexagonal columns

Conservation Note
This area is part of a UNESCO Global Geopark—avoid removing rock or coral, use reef-safe sunscreen, and follow guide instructions to minimize impact.
Sai Kung’s coastline reflects a long maritime tradition of fishing and boat-building; the volcanic columns record dramatic eruptions and rapid cooling of basaltic lava in the region’s geological past.
