Sunset & Bioluminescent Plankton Kayaking in Lan Ha Bay
Imagine paddling through dark waters illuminated by tiny, glowing creatures — a natural light show that’s as enchanting as it sounds. For those exploring Vietnam’s northern waters, this tour in Lan Ha Bay, near Cat Ba, offers a rare chance to witness bioluminescent plankton firsthand. At just $43 per person and lasting around 4 hours, it’s a compact adventure that packs a punch for anyone craving authentic natural beauty and a touch of magic.
What we love most about this experience is how it combines different elements — a scenic sunset dinner on the beach, a fascinating visit to a floating village, and the thrill of kayaking in the dark while the water lights up beneath you. The tours are well-organized, covering transportation, dinner, and all fees, which means you can focus solely on enjoying the moment.
A potential consideration? The timing is key. Since the bioluminescence is best observed after sunset, this tour starts late in the afternoon, which might be tricky for early risers or those with tight schedules. Also, since weather can affect the experience, it’s wise to be flexible or prepared for possible rescheduling in poor conditions.
This tour is ideal for nature lovers, adventurers eager to try something truly unique, and anyone who appreciates authentic coastal scenery. It’s especially suited for travelers who want to combine a bit of culture (floating village visit) with natural wonder, all while enjoying a relaxed, small-group setting.

The Itinerary: From Land to Light
The adventure starts in Cat Ba, a lively island known for its dramatic limestone karsts and fishing villages. Your pickup begins at 3:30 PM from the designated meeting point, Beka Travel’s office in Cat Ba town. From there, a comfortable air-conditioned vehicle transports you to Beo Harbor—a scenic spot that’s the gateway to Lan Ha Bay.
The boat ride through Cai Beo floating village is a highlight in itself. Watching local life unfold on water, with floating houses, fishing boats, and possibly playful monkeys, sets the scene for the natural wonders to come. The boat then heads towards Van Boi beach, where you’ll settle in to enjoy a beautiful sunset. The sunset is more than just a pretty view; it’s the backdrop for a beachfront BBQ dinner that’s included in the package.
Once dinner is underway and the sun has dipped below the horizon, the real magic begins. You’ll board a floating house—a sturdy platform on the water—to start your kayaking adventure. Led by a knowledgeable guide, you’ll paddle into the darkness, where millions of glowing plankton light up your water trail.
The experience is flexible—if you fancy, you can even take a swim and see your own bioluminescent silhouette. Many reviews mention how strong and mesmerizing the plankton glow is, with some travelers describing it as “incredible” and “such a fun experience.” After about an hour of kayaking and exploring, you’ll head back to the floating house to start your return journey.
The tour wraps up with a speed boat ride back to Beo Harbor, followed by a comfortable drive back to your hotel. The entire process, from pickup to return, is designed to be smooth, with all fees covered, so you can relax and enjoy the scenery.
