Great Experience - My daughter and I had an amazing time. It was definitely a new experience but really worth it. The entire staff was great especially Javier and Jariel. Thank you. Even if you have never done this before, they made sure to help every step of the way.

Sunset paddling - Yadiel, Javier, Amaury & Natalia were an amazing team. They were all knowledgeable and helpful throughout the tour. They worked with us and warned of low luminosity this week. The kayak experience itself was amazing. First you paddle through a channel surrounded by mangroves. Then you end up in a lagoon. We got to watch the sunset in the lagoon and paddle around before gathering around to hear about the stars the glowing algae. They had a tarp so the we could block out the moon and have total darkness to look for sparks in the water. Then we paddled back through the mangroves to the starting point. The guides were always nearby to help those who needed it and to share stories with others.

We unfortunately did not... - We unfortunately did not get to see any bioluminescence due to a recent storm. However, the night kayaking was still fun! We did get to learn about constellations and enjoy a nice night out. You WILL get wet from the waist down, so plan accordingly.

First time kayaking - This was a great experience! We are not experienced kayakers and could not quite get the swing of it, but the excellent guides, Jadiel and Javier, took extra care to be sure we were safe and assisted us through the ride. It was a beautiful ride through the mangroves and to the bay. Although we didn’t see much, if any glow, it was still a magical experience. Great for stargazers too as Javier showed us all the visible constellations with his laser light. I can’t say enough about the knowledgeable, friendly and fun guides, Jadiel, Javier, Amaury, Christian and Natalia (the super sweet hostess.) They provided bug spray and water and chips too. I can’t recommend this tour enough, especially if you are inexperienced as we were. We felt completely safe in their care. This was our second ‘Pure Adventure’ tour and I will definitely use them again for future excursions- it’s a first rate company. Thank you again Jadiel and Javier for taking care of us, as well as the rest of the team! Cheers!

Good ethics company - Booked but did not go. The company let us know that there was no glow the night before and offered a full refund, which was very much appreciated.

Interesting experience - This was an enjoyable tour, but unfortunately the bioluminescence was absent. The sunset was my favourite thing as they timed the kayaking through the mangroves perfectly. It was tricky coming back in the dark through a narrow canal and with mosquitos, but I enjoyed the experience. Not for the faint-hearted.

It was a fun time... - It was a fun time considering it was my first time kayaking. The weather was nice. The water felt refreshing. I just wish there was more bioluminescence but it wasn’t anyone’s fault. My favorite part was how engaging our tour guides were: Eli, Amari, and I forgot the name of the third gentleman.

This would have been a... - This would have been a fun excursion, but it was extremely crowded with way too many kayaks trying to maneuver through a narrow mangrove channel in the dark. It can best be described as bumper kayaking. The guides did the best they could under the circumstances.

Cancelled event same day - The event was cancelled day of. So I’m hopeful we will get our refund. Many people say that when they have gone there is very little glow of any at all. Not sure which was more disappointing. Not getting the experience at all or going and seeing nothing? If I see my refund then I’ll be glad.
