Wicked good bioluminescence kayaking tour - My 15 year old daughter and I did this trip. Our tour guides were funny and informative. The paddle out was pleasant. At the lagoon, we learned about the bioluminescence, learned about the constellations, and finally put a tarp over our kayaks and saw the bioluminescence. My daughter said that it was a bucket-list level experience. I agree. Thank you!!

Bioluminescence and Bus Trips - Such a fun experience! The guides were so engaging and informative! The mangroves were really cool. And of course, the light up plankton rocked. I only want better snacks. Everything else was awesome. Props to the bus driver. 10/10 playlist, nothing but bops. Louder for the people in the back.

It was lot of fun.... - It was lot of fun. Kayaking at night is more difficult but our guide Zaer (name probably spelled wrong) was very helpful. He steered our kayaks both directions. Even though we had gone on a no moon night - we saw very faint light while kayaking. Once they covered us with a tarp we really saw the luminosity. We could see sparkles while kayaking but saw real bright luminous water when covered with tarp.

Impressive company. The... - Impressive company. The presence of a full moon during our visit to observe the bioluminescence may have made it difficult to detect any changes in the water, but this company thought ahead and provided a tarp to shield the group, ensuring that we could fully enjoy the experience we came for.

Awesome - This was a great experience. The guides made sure everyone had fun and were able to see the glowing water even if the conditions weren’t ideal. Definitely would do it again.

Challenging, Be understanding of nature. - You couldn't see much of the bioluminescence when we went, but that was out of our control. The moon was almost full. Regardless, our tour guide did everything he could to get us to see it, and we could still see the sparkles after putting a tarp across our kayaks and playing with the water. The kayaking was fun. Heading out to the lagoon was easy (I have experience kayaking) but heading back to base was challenging. The current was against us. If you are up for the challenge and understanding of nature, it is still a great experience. Our toue guides were hilarious and knowledgeable. We had a great time.

Staff at kaoke was good and helpful - Had rough time with the person for the transportation. We did not like the ride, we were first ones to pick and last ones to drop

Visibility bad with moon light. - If the moon is out don’t expect to see anything. Our tour guide had a tarp for us to put over our kayak to see but still not good.

The activity itself... - The activity itself wasn’t bad however communication wasn’t the best (I texted and asked about proper attire, told there was no specifics just to end up having to remove what I was wearing). At the end of the trip my bus wasn’t allowed to move due to someone not paying causing me to lose money on other planned activities
