A cruise tour in Hong Kong with Splitdyboat means a pure sightseeing experience where you stay on the boat and enjoy the views, without any kayaking or snorkelling activities. You can relax on board, take photos, and listen to the guide’s commentary while the boat cruises past the UNESCO Global Geopark’s volcanic cliffs, sea arches, and islands.​

.

The Geopark Four Sea Arches Yacht Edition is also considered a cruise tour: the focus is still comfortable sightseeing from the yacht, but there is an optional short walk on one of the islands to stretch your legs and get closer to the rock formations. If you prefer to stay on board, you can simply remain on the yacht during the island stop and continue enjoying the scenery from the deck.​

Yes, actually suitable for all ages.

Splitdyboat’s cruise tours are relaxed sightseeing trips that are suitable for all ages, including young children and elderly family members. Guests stay comfortably on the boat while enjoying the scenery, with seating, life jackets, and commentary provided, and any short island walks on the yacht edition Four Sea Arches route are completely optional so those who prefer can remain on the yacht throughout.

Hong Kong’s cruise tours take you into the Sai Kung Volcanic Rock Region of Hong Kong UNESCO Global Geopark, home to the world’s largest concentration of hexagonal volcanic rock columns, covering around 100 square kilometres on land and under the sea. These towering, tightly packed columns can reach up to about 30 metres high and over a metre wide, creating dramatic sea cliffs and arches that look almost unreal from the boat.​

.

These columns were formed about 140 million years ago when a super‑volcano in what is now Sai Kung erupted, collapsed, and left a huge caldera where hot volcanic ash slowly cooled and cracked into hexagonal joints, a process known as columnar jointing. The area was recognised as Hong Kong UNESCO Global Geopark in 2011 and later selected as one of the “First 100” IUGS Geological Heritage Sites, highlighting its global scientific and scenic importance.​

.

Key routes include the Geopark Four Sea Arches Volcano Sightseeing Tour and other Sai Kung island‑hopping boat and yacht experiences that depart from Sai Kung town and cruise around High Island, Po Pin Chau, Bluff Island, Jin Island and nearby inner‑bay islands.

For Splitdyboat cruise tours, guests should dress light, protect from the sun, and be ready for sea breeze and occasional splashes. Here is a simple checklist by tour type.​

.

Speedboat Edition Geopark Four Sea Arches Volcano Sightseeing tour

• Comfortable light clothing (sportswear / quick‑dry T‑shirt and shorts; avoid long skirts).​
• Windproof layer or light jacket in cooler months (it can feel windy on a fast boat).​
• Non‑slip sandals or sports shoes that can get a little wet.​
• Sun protection: reef‑safe sunscreen, hat, and sunglasses.​
• Reusable water bottle and optional light snacks.​

.

Yacht Edition Geopark Four Sea Arches Volcano Sightseeing tour

• Casual resort‑style clothing or light sportswear; bring swimwear and towel if the route includes optional beach or water time.​
• Comfortable sandals or deck shoes (avoid high heels).​
• Sun protection: sunscreen, hat, sunglasses, plus a light cover‑up or UV shirt.​
• Reusable water bottle; check your product page for whether drinks/food are included or if you can bring your own.

During autumn and winter (roughly November to March)...

the speedboat edition of the Geopark Four Sea Arches Volcano Sightseeing Tour usually pauses due to cooler, windier sea conditions, while the yacht edition cruise continues to operate with adjusted schedules. For yacht departures in these months, guests are strongly advised to bring a windbreaker, warm layers, and a light hat or beanie to stay comfortable in the sea breeze on deck.

No. Cruise tours are pure sightseeing trips, so there is no need to swim and no water‑entry activities are required at any point. Even on routes with an optional short island walk or beach stop, guests who cannot swim or prefer to stay dry can simply remain safely on the boat and continue enjoying the scenery.
