Paddle through a 40‑meter sea tunnel and around dramatic hexagonal basalt columns in Hong Kong’s Ninepin Islands. This guided full‑day tour combines speedboat transfers, basic skills coaching and focused sea‑cave exploration in a UNESCO Geopark.
More ways to explore the area's outdoor wonders
You push off from Clear Water Bay Second Beach as the city’s edge slips behind you and the sea opens into a raw, basalt-carved world. The kayak hums over turquoise shallows, and soon a 40‑meter tunnel yawns ahead — the Three Dragon sea cave — a dark throat cut through columnar basalt that challenges you to paddle into its hush.

Watch the wind and tides
Operators cancel in high winds—check the marine forecast and expect tidal currents near cave mouths.
Wear grippy water shoes
Cobbled basalt and wet decks require footwear with good traction for beaching and short rock hops.
Protect camera gear
Use a dry bag and secure straps; caves create spray and sudden reflections that challenge phones and DSLRs.
Bring extra water and snacks
Six‑hour outings and sun exposure demand more hydration than you’ll think—pack 1–1.5 L per person.
Dry bag (10–20L)
Keeps camera, phone and layers dry through spray and cave passages.

Grippy water shoes
Protects feet on wet basalt and provides traction when landing on rocky shores.
Sun protection (hat, sunscreen)
Open water exposure intensifies UV—apply and reapply throughout the day.
summer
Insulating layer or windbreaker
Light windproof layer reduces chill when paddling across open channels.
