Overview of the Experience

This tour typically begins with hotel pickup in Cat Ba Town, after which you’ll be transferred to Beo Harbor. From there, a support boat takes you to a quiet cove in Lan Ha Bay, specifically in the Van Boi area. The boat ride alone offers stunning vistas of the bay, setting the perfect stage for what’s to come.

Once onboard, the crew prepares a Vietnamese dinner — vegetarian options are available — while you relax, take in the sunset, or enjoy a swim at one of the designated beach areas. Around 6:15 pm, you’ll receive a safety and eco-briefing from your certified guide, who will equip you with a life jacket, paddle, and headlamp (no light pollution, so the bioluminescent plankton can shine brightly).

The highlight is the guided night kayak through calm lagoons. As you paddle slowly and quietly, each stroke stirs the water, igniting the tiny glowing plankton that have made Lan Ha Bay famous for its luminous waters. It’s a surreal, almost otherworldly sight that’s best on dark nights with little moonlight, and your guide will select dark coves for the most intense glow.
