5.00This was truly a unique experience you can only see or do a few places on the world! Arun and Pepe were TOP NOTCH guides that were very low key but had a great sense of humor. More importantly, they were safety- and comfort-conscious to the point of personally assisting those who were a little more unsure in the water. Highly recommended!
Fun night exploring the bioluminescence

5.00Our tour guides Aaron & Pepe were great. They provided great information throughout our excursion and gave us extra time to explore at Star fish point. They were safety conscious to make sure the guests were comfortable with the sea life and being in the water.
Worth the price

5.00At first I thought the price tag was a little high, though this excursion was definitely worth it. I wanted to do this as a DIY, but for this experience it's not really possible. The bioluminescent bay is surrounded by private property, which makes access only possible by boat. Swimming with each movement producing blue light was a worthwhile experience. Additionally, they provided us swimming gear to prevent us from being stung by jelly fish. Very cool experience, would highly recommend. Much more fun that Stingray City (which I also experienced).

Great time at Bioluminescent Bay

5.00Amazing, well worth it. Captain Marvin's crew were great. If you are freaked out about swimming in the dark, take the pool noodle they provide. Swimming under the boat gave the best results as it was even darker. We had virtually no moon light so it was a good time to go.

5.00Starfish point was very fun. The water was warm and you could stand on the sand. The bioluminescence tour was a very unique experience, very neat and was able to see my hands glow in the dark.
Best tour on the island!

5.00Amazing! I totally recommend it. The water is not cold and every time you move you see the color! And the guides Pepe and Aaron were great! Very nice all the time and informative. They are bilingual (English and Spanish) so it was helpful for me that they explained some things in Spanish.
