Cai Beo is one of the bay’s oldest floating communities, with a fishing culture that has persisted for centuries; the karst islands formed as marine limestone was uplifted and eroded over millions of years.
Conservation
Lan Ha Bay’s ecosystems are sensitive—minimize plastic, use reef‑safe products and follow guides’ rules to reduce disturbance to bioluminescent organisms and nesting birds.

Bring a waterproof headlamp
A dim red or low-power headlamp makes boarding, changing, and night navigation easier without disturbing bioluminescence.
Use reef-safe sunscreen
Lan Ha Bay’s marine life is sensitive—choose biodegradable sunscreen to reduce chemical runoff.
Protect electronics
Store phones and cameras in a dry bag; brief shots of the glow are possible but expect long exposures to be difficult on a moving kayak.
Dress in layers
Even in summer, evenings on the water can be cool—bring a light wind layer you can stow in a dry bag.
Waterproof dry bag
Keeps clothes, electronics and documents dry during transfers and while kayaking.
