FAQs about the Cat Ba – Lan Ha Bay Bioluminescent Tour
1. What makes the Lan Ha Bay Bioluminescent Tour different from a regular evening cruise?
Unlike a standard sunset cruise, this tour offers the rare chance to witness glowing plankton lighting up the water at night.
You’ll kayak through calm, dark waters and watch the sea sparkle beneath your paddle — a magical natural effect caused by bioluminescent microorganisms.
2. Can I really see glowing plankton every night?
Bioluminescence is a natural phenomenon, so visibility depends on water clarity, moonlight, and weather.
The best chances are during calm, dark nights between May and September when the water is warm and clear.
3. Is the night kayaking activity safe for beginners?
Yes. The tour is beginner-friendly. You’ll receive a safety briefing, wear a life jacket, and be guided by experienced staff who stay close during the entire paddle.
The kayaks are stable, and the water in Lan Ha Bay is usually calm at night.
4. What should I wear for the bioluminescent kayaking experience?
Lightweight, quick-dry clothes are best. Bring a towel and a spare outfit for after kayaking. Avoid wearing heavy shoes; sandals or barefoot are fine.
A light jacket is also recommended for the cool evening breeze.
5. Will there be food or drinks provided during the tour?
Yes, a freshly prepared Vietnamese light dinner is served onboard. Drinking water is included, but guests can purchase additional beverages if desired. The meal often features local seafood, rice dishes, and seasonal vegetables.
6. Do I need to know how to swim to join the tour?
