Paddle into the twilight among Lan Ha Bay’s limestone karsts and watch the ocean ignite with blue bioluminescent plankton. This guided sunset cruise and night kayak combines easy paddling with a rare natural light show—and practical tips make it accessible to most travelers.
More ways to explore the area's outdoor wonders
You push off from the boat as the last sun drops behind jagged limestone karsts, and the water around your paddle briefly lights up—tiny blue sparks that seem to follow your movement. In Lan Ha Bay the islands crowd the horizon like dark teeth, and the evening wind carries the smell of salt and cooked fish from nearby floating villages.

History
Lan Ha Bay sits adjacent to the Ha Long UNESCO area and has long supported floating fishing communities and aquaculture; many camps and craft still follow traditional patterns.
Conservation
Bioluminescent plankton are sensitive to light and pollution—avoid using soaps in the water, follow guide instructions to minimise disturbance, and support operators who practice low-impact boating.
Reserve your spot on the Sunset and Plankton Bioluminescent Night Kayak Lan Ha Bay today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Time the moon
Choose a night near the new moon—less moonlight makes plankton easier to see.
Keep lights off
Turn off flashlights and phone screens during the night paddle to avoid washing out the bioluminescence.
Bring a dry bag
Stash electronics, a light jacket and snacks in a waterproof bag to stay comfortable after the sun sets.
Hydrate and eat beforehand
Have a light meal and water before boarding—the trip includes dinner but paddling uses energy and it can get chilly after sunset.
Waterproof dry bag
Protects phone, camera and a change of clothes from spray and unexpected splashes.
Headlamp with red light
Red setting preserves night vision and won’t overwhelm the plankton; keep it off during viewing.
Light, waterproof jacket
Night temperatures can drop and a windproof layer blocks spray and chill.

Reusable water bottle
