Unexpectedly amazed

5.00The bay was amazing and the team made me feel safe as kayaking at night with complete darkness was a new experience for me!
Don’t BOOK!

1.00Do not book this tour! Horrible customer service. Very inconvenient. 1.5 hr ferry ride to get to the island. They don’t tell you this when booking that the last ferry back is at 9:30pm and they have an 8:00 time slot. Which means if you book it you’re stuck on the island all night! Their customer service is horrible and very unfriendly.
Bucket List Experience

5.00We had a great experience! We took our 4 kid, ages 9-15. The trip was smooth and well organized. Our guide took time to explain the science behind the microorganisms and even brought a light blocking cover for our kayaks to really experience the full effect! If possible, try and go on a night with lots of cloud coverage/minimal moonlight. When the clouds covered the moon, the glow was much brighter. Great bucket list item checked off!
Biobay amazingness

5.00Amazing experience, be sure when you book, that you’ve paid attention to the lunar cycles and the weather as much as as possible. Go whenever there is no moon or a new moon.
Lovely experience seeing the Bay

4.00Very well organized.. wish we had more time to just paddle vs being all connected most of the time but also get that the winds were high and not everyone is an experienced kayaker. Bay was very neat! Stars spectacular! Timon (I think that was his name?) was an amazing guide! Great conversation and wonderful sense of humor.
Well organized, but didn’t learn much

3.00Tour was well organized but guides were difficult to understand. Would have liked to learn more about the bioluminescence bay and its history. Overpriced for the quality of the tour
Attempted to get a refund...

1.00Attempted to get a refund and couldn’t get in contact with anyone until the day of scheduled activity. Viator claimed that the tour refused to refund, the tour said Viator was lying and never spoke to them and Viator could issue a refund. Both parties blamed other party. Tour offered me a free excursion for the family if we ever returned to PR due to Viators actions however we live about 7-8 flight hours away so no chance that’ll get occur. Viator said they called the tour to get refund and your owner said they never did, Viator and the tour also didn’t disclose an important detail that a person would be stuck on an island an hour away with later tour. It was all a mess start to finish. We won’t use Viator ever again.
Highly recommended! Unforgettable experience!

5.00An unforgettable experience! They left us longer than we expected in the water and our guide's explanations were excellent! The only bad thing was that in our group there was a drunk couple who were very reckless with kayaking, I think they should not have allowed them to take the excursion, because they endangered the rest of the group. Except for that, the experience was very good. Ideally, do it on a cloudy or new moon day so that the sky is very dark. We loved it!

5.00Bioluminescence tour excellent trip to see. Place to visit during moonless night is the best time to plan. Clear sky and star viewing is fun too
