Blue Lights were not lighting

It was a pretty long drive and barely saw the lights unfortunately. It was a beautiful night but no luck with blue lights.

Skip it!

This excursion was extremely disappointing and poorly organised from beginning to end. First, the driving behaviour of the driver who transported us was completely unacceptable, particularly on the return journey, when he appeared to be in a hurry to get back. His reckless driving made us feel extremely unsafe. Second, we were taken to the departure point 2.5 hours before the cruise, for absolutely no reason. We were left waiting unnecessarily, wasting valuable holiday time and effectively losing an entire day due to extremely poor planning. Furthermore, the captain could not communicate in English, the safety measures on board appeared inadequate, and the boat itself was dirty and poorly maintained. Most importantly, why do you continue organising and selling bioluminescence tours when you know that the moon conditions and the location make it practically impossible to observe the phenomenon? This is extremely misleading and unfair to customers who pay specifically for this experience. I would strongly advise others to avoid this tour.

Bio Bay EXPERIENCE

It was somewhat of a let down not having to see the bioluminicense in effect, the moon light may have a factor, not sure if it will be he same case during new moon. Was not visible when others swam on the bay. The captain tried to show the luminescent affect of rhe watter bringing some buckets in the boat, but was not much either. Maybe wrong time to do this with the moon going to full-term. They should have this only during New Moon when the moon does not give light. But then its business and tourism. But having disappointed customers and tourists does hurt the attraction. Not much of activity also in the tourist spot with most of the restaurants and businesses closed. The center does give a good time to take pictures. People and vendors we're really nice and helpful.

Don’t Book This!

You don’t see anything, a complete waste of money. If you want a boat ride in the dark this is for you.

Beautiful, fun, clarify the meeting point

Everything worked out perfectly, and it was an amazing experience. Plenty of time to swim and experience the bioluminescence - bring goggles for more of an experience. My only criticism is that they could have clarified the meeting point a little more. You're not meeting at the restaurant, there's a booth at the end of the pier from the restaurant. I had to ask around a little to find it, but we still had plenty of time until the boat departed, and the crew was very friendly.
