    One of our best experiences in Vietnam!

    This was such a fun tour! Our guide Cong (sorry if that’s incorrect) was THE BEST and so knowledgeable, and the whole process with Cat Ba Ventures was very smooth from start to finish! We were also lucky enough to see the bioluminescent plankton and they were magical!! A must do if you’re in Cat Ba!

    Beautiful bioluminescence trip

    Great trip, which we booked with our group of swimmers. Our guide Ben was very friendly, open minded, knowledgeable about the local area, and always helpful. Nice sunset swim from the boat to a tiny beach and back. Absolutely stunning experience of bioluminescence by night from a kayaker's perspective. Had time to explore and play with the glowing plankton in multiple spots. Speedboat ride (including more bioluminescence) back to dinner on a floating restaurant.

    Bioluminescent plankton tour

    I was looking for an operator for night time plankton tour and cat ba ventures still operate. It was a Highlight for my family. The buoluminescent plankton was magical and abundant. The tour guide Viet was funny and helpful. Couldn't have planned a better trip.
