Unfortunately the moon was full so to see them we had to go under a tarp our guides provided. We could see them then but the best part was going back through the mangrove in the dark with the moon coming through the mangroves. Amazing sight! read less

We started off at about 615 in the dark. Once we reached the mangrove canal it was pitch dark. It was easy to paddle right into the tree branches as you can not see anything unless the hide flashes his light.
Once we got to the lagoon we were told to put a tarp over our heads to see the glow of the organism. We could not have stayed for more than 15 minutes. It would have been nice if they did not rush us back. The tour company has another late night tour which they have to get back for.
The glow is not like what I had imagined. It was more along sparks from static electricity. Other reviewers wrote that it was amazing. I did not feel it was very spectacular but it might just be the night we were there.
What was spectacular was the experience of kayaking at night through the mangrove canals.
I wouldn't say the guides were informative or went out of their way to make you feel comfortable. They were just their to lead the way.
Overall enjoyable. read lessAtlantaLucky711/27/2015Great! The guides were excellent. They made sure everyone was safe and had a good time. The kayak ride up to the lagoon was enchanting.

Los monitores estuvieron muy pendientes de nosotros todo el rato y nos instruyeron en cada momento. El viaje hasta la laguna fue muy divertido, y una vez allí, nos contaron acerca de la fauna y flora de la zona. Nos hicieron un truco de magia, donde vimos el agua brillar (algo que realmente nunca había visto anteriormente y fue una experiencia mágica...)
La vuelta es contra corriente y a oscuras: Se requiere un poco de fuerza en los brazos, pero los monitores siguen estando muy encima tuyo, sin dejar que te pierdas.
No es para nada peligroso y ellos te van iluminando el camino.
Volvería a repetirlo sin duda! read lessLaia S7/02/2019It's unique! Bioluminescent kayak tour! This is a lot of fun and an experience you'll never forget. Nothing else is like it.

Everyone has been talking about it with awe and excitement since! There were a few who had never kayaked before, and they were shown extra care and attention and were so proud they concurred fears and had the opportunity to experience overcoming fears with someone by their side. The bioluminescent bay was exciting to see and looked like glitter and sparks in the water. It was interesting to hear about the impact of hurricane Maria and the effects on the bioluminescent bay plankton.
For those looking for details: yes you get wet from waist down. Bring a towel and change of clothes. If you go at sunset, bring bug spray - we used bug spray and no one came away with bites. Yes, it can be tiring paddling back, but you will be proud of what you can accomplish. Nestor and his crew will take good care of you! read lessWONDERandWONDER7/21/2019Great staff and beautiful bioluminescence! The staff were very knowledgeable!

The bioluminescence was super bright, and I appreciated the tarp they brought (that we could put over ourselves) to eliminate all the light pollution. Nestor was an excellent guide! You have to walk out into the water (about waist deep), but I honestly feel it added to the exciting experience. Paddling down a long channel into an enclosed lagoon felt very intimate with the surrounding nature, and being in the lagoon felt safe (i.e., no big boats, no chance of drifting into the ocean, etc.). read less

We had been kayaking before as had most of the tour group, so it was pretty smooth getting out there. There are some low branches and things that are in the way, but the guides knew where they were and made it really clear to us so that everyone was able to avoid them without a problem. The one thing that I did not like was using bright white flashlights to show us things. It made them easy to see, but also kept my eyes from being able to fully adjust to the dark which made navigation in the narrow places a little more challenging.Going during a new moon would be ideal, but we were able to see a lot while we were there, too. The bioluminescent bay was really cool and we were able to see it a little without the tarp, but the tarp definitely amplified the effect. read less

That being said, it was a great experience and I highly recommend it. Be sure to book directly with the company to save money. We saw signs on the beaches through a tour company for the same tour we took for $30 more than we paid. If you need a bite to eat beforehand, there is a guy who grills chicken and has rice and beans for $6 a plate right next to the booth where you check in. It was the best food we ate all trip. The pina coladas were excellent too ($4). read less
