  • "I do not recommend going with a kayak partner that cannot help row as on the way back you have to fight the current and its pitch black." See review
  • "Definitely bring water shoes and be prepared for a workout!!" See review
  • "Also if you’re afraid of the dark, take an earlier tour to at least have daylight on your way in under the trees, and then darkness on the way back." See review

The guides were very patient and great! We enjoyed the kayaking and by innovatively covering each kayak with tarp helped see the bioilluminescence.

A beautiful paddle in and out of the bay
, Jan 2022
This was a fun kayak out to the bay, a look at the bioluminescence algae and the stars, and a kayak back. As others have said, it’s not worth having your camera/phone - just take it in. We had a fantastic time. We give four stars just for the overall experience compared to five stars doing the waterfall, water slide and jungle hike experience. This company did a fantastic job and the guides were great. Your experience will likely depend on luck - the phases of the moon, tide and cloud cover. But definitely worth doing once.
Both the women guides were closer to us, and they were the best! They said their names. But We can’t

The guides were great; we had a traffic jam/accident so I text and we still made it for for the orientation. We didn’t see bright glow like the pictures, but a faint glitter on the moon lit night. I wish the orientation would have told people not to use flash ahead of time— because I was next to someone who ignored the guides request to not use flash. My friend who came with wasn’t sure she would recommend, because she thought it was a little too hyped up about the chance to see, but it was a fun experience overall.
A pleasant tour
, Jan 2022
The tour was amazing. Chose 8pm tour. Even though we were the first time Kayaking, it was manageable thanks to the staffs. At the beginning we were so struggle and could not go straight, hitting the trees. It was completely dark and we were slow, way behind of the group. As soon as we felt desperate, one of the staff came and helped, cheered us. With those helps, we finally understood how to go straight and manipulate the kayak. After all, we enjoyed the trip. The staffs were great!!

Magical experience- DO NOT MISS IT!
, Dec 2021
This was an incredible experience! Paddling through a mangrove channel in pitch darkness, seeing the sparkles in the water from the bioluminescence, hearing all around us the splashes of fishing bats grabbing a nighttime meal punctuated by the sounds of kayakers paddling - it was magical, otherworldly. Our guides Javier and Sandra provided excellent commentary on the night skies and constellations as well as the bioluminescence and ecosystem. The team kept us all safe and helped us navigate the channel in the darkness. We had all levels of kayakers on this trip and everyone did ok, despite a few folks getting a little stuck in the roots a few times. The team got them quickly back out into the middle of the channel and nobody capsized or anything dramatic. It was an amazing time!

Hello friend! This is an excellent review, it captures the essence of the whole adventure, we truly appreciate it. Thank you very much for joining us. Cordially Yolanda Ramos PURE ADVENTURE
Memorable once in a lifetime experience!
, Dec 2021
This tour went above and beyond my expectations. Our guides (Sandra, Natalia, and 2 others) explained instructions well prior to departing, and made sure everyone was safe and together. We got to see the bioluminescence, as well as all the stars on the clear sky! The only downside was on the way back, there was a little traffic jam with other tour companies, which we had to watch out not to bump into trees or other people's kayaks. We booked the 6pm tour and was perfect.

Hey YuAnn_W, Thank you very much for your wonderful review ;) PURE ADVENTURE TEAM
Bio Bay ! Pure Adventure was amazing !
, Dec 2021
This was a beautiful experience. Stars above us and glowing algae below .. magical. However , be prepared this is a work out and not for those who have never kayaked. Guides were phenomenal. Sandra was super informative, funny and great. unfortunately I don’t recall the names of her team, but everyone was perfect. It was too dark to film and so I feel like it was all a dream. Amazing experience!

Great experience
, Dec 2021
We were nervous at first to be kayaking late at night but WOW!!!!! It was such an adventure from start to finish ! We saw the sparkles 2/3 of our trip and once we got to the lagoon we had a perfect night to look at the stars. The tour guides were amazing and knowledgeable! We really enjoyed this experience and glad we made the 2 hour drive from our resort !

Please Don’t Go If You’ve Never Kayaked Before
, Nov 2021
These tours should be reserved for experienced kayakers. There were multitudes of people on this tour who had never kayaked before. Kayaking for the first time ever in pitch black conditions is not only a bad idea, but extremely unsafe. My husband and I, along with our friends, have kayaked multiple times before and were very disappointed that this tour allowed people who had never kayaked before to join. Lots of traffic in the canal in the dark while trying to dodge people who clearly did not know how to kayak were causing issues in the waterway making it a bad experience for everyone. Also, SUPER DANGEROUS despite it being less than 3 feet of water. The guides who are supposed to lead the way and alert kayakers of turns, tree branches, and underwater hazards were instead forced to help straggling first-timers keep up with the group. Companies are only out here for the money, so I guess at the end of the day, you get what you pay for.

Dear Shannon_S, Thank you sharing your feedback. I'm truly sorry the experience was not what you expected. Unfortunately, even though we strongly recommend inexperience kayakers to chose the early tour, many decide to take the later one. Our guides work really hard to assist the group through the entire experience, but keep in mind that we cannot control the organization of the other group companies. Not every night gets that busy but from time to time or during holidays it is expected to be crowded, a detail that we also cover in our webpage for the benefit of our guests. Another strong detail we mention in our webpage is the darkness, especially in the later tour. Still, many guests decide to take it thinking that it may not be that dark, but it is absolutely pitch dark. Regardless, I will share your feedback with our operations manager hoping we can avoid this from happening in the future. Cordially, Yolanda Ramos PURE ADVENTURE

I was very much looking forward to showing my husband the bioluminescent bay which I was in awe at when I went as a kid. Unfortunately, we did not have a positive experience. This tour was so chaotic from the start. There was a brief kayaking tutorial and we were in a mad rush off. There was so much traffic due to the number of kayaks that were going through the very narrow canal and the darkness did not allow for you to clearly see where you were going. I completely understand that the later start time (8pm) means that it’ll be dark, but there should be a call out that says this time slot should be reserved for very experienced kayakers especially given that it’s already challenging due to the narrow passageways. We truly could not enjoy the bioluminescence of the bay due to the stressful nature of navigating the kayak and evading the other kayaking companies coming the other way. I truly hope the tour company takes this into consideration by downsizing groups and limiting the later slot time to experienced kayakers to avoid the chaos and make for a more enjoyable experience.
