A cool experience for our family

Abigail_L, Mar 2024

Our family of four (two adults, 13yo, 7yo) really enjoyed this experience. We have kayaked before but are not experienced by any means. The guides were super helpful and knowledgeable. It was a bit of a workout, but totally worth it! The 7 yo was nervous given how dark the excursion was navigating through the mangrove, but was enthralled once we started seeing the bioluminescence created as our paddles pushed through the water. Plan to get wet and to get a good workout in! The snack/food stand was nice to enjoy a quick beverage and bite to eat before we headed out. The description of this excursion was good and we felt well prepared for the adventure.

Awesome

Dya_J, Feb 2024

Had a great time! The tour guides were awesome! Kayaking in the dark was the best part! You could see the bioluminescence but not as bright as I thought.

Magical Experience

Rachel_R, Jan 2024

Kayaking is definitely a team sport, so it's helpful to come with someone you're ready to work with! We had a wonderful time especially because we embraced the feeling of bumper-kayaking at night (expect to crash into other kayaks and trees!). Once we got to the bay, it was truly magical. I recommend looking at what phase the moon is in when planning this trip to make sure you have the best chance at seeing the bioluminescent bbs. The tour guide team was fun and patient with us, and even though the tarp moment felt a little clumsy - the ability to see the bioluminescence in total darkness was really magical. We had such a lovely adventure and I'd love to do it again!

The tour guides were very friendly and helpful. It was a great time and I’d recommend it! The bio bay was beautiful

Fun and unique adventure

Michelle_P, Dec 2023

We had an awesome time kayaking through the bioluminescent bay. Our guides were skilled, helpful, and entertaining. Emily was especially knowledgeable (and funny) and shared a lot of interesting information about why and how the bioluminescence occurs. Even though the moon was pretty bright, we had a fun time kayaking and we could still see the bioluminescence. The magic really happened when the guides brought out tarps to create true darkness so that we could appreciate the phenomenon. That was amazing! We were all fascinated by the individual lights like pieces of glitter. If you are in Fajardo, you should experience this.

Super cool experience!

Megan_S, Nov 2023

Amazing experience! Under the tarp the bioluminescent organisms look like fairy dust or glowing glitter. Guides were fantastic. Garef helped us when we got stuck and gave us a tow back. Highly recommend!

Douglas_S, Nov 2023

This was amazing! The kayaking to the bay was easy and the bioluninescent organisms were visible all the way to the bay. The glowing jellyfish were so fun, too. We didn't know we would have those there, which made it even more amazing. I don't know if they ate at the other bioluninescent bays, but there are tons of them in this one. They don't sting, so we could catch them and hold them. Truly a once in a lifetime experience. The darker the night, the better; best to go with no moon, bit go either way, they will provide tarps to see better. We went about 4 days after no moon and we were able to see them, but with the tarps they provided to put over us, it was super amazing. All the guides were great. Highly recommend this tour!!!

Awesome!

Taylor_B, Oct 2023

Emily and the entire crew was incredible! We had the best time and would absolutely do this experience again!

just book it

Alba_B, Sep 2023

I loved this activity! All the captain were very knowledgeable and they were always alert. I am HORRIBLE at coordinating and they made the experience seemsly. I will definitely book with them again. I enjoyed it so much .

Magical experience

Jaclyn_W, Jan 2023

Fun experience kayaking under the moonlight. I found this to be peaceful and magical paddling through the mangroves. My husband and teenage daughter on the other hand were surprised with such a workout. It’s 90% kayaking through the mangroves and 10% seeing the micro organisms. I wish there was a heads up of what to wear… you step in the water up to your ankles, and you get soaked from the waste down from sitting in the kayak and having water drip all over. Wear flip flops and bring a change of clothes. No flashes are allowed, so no need to go through the trouble of water proofing your phone. Altogether a good time.

Response from Host, Jan 2023

You will get wet participating in any activity involving a beach, river, pool, or anything else with water. Being mindful that this is a night kayaking tour through a mangrove forest, please dress accordingly. We publish information in the tour description and SMS notifications in an effort to raise awareness of the activity. Please read the text we send you for your convenience in addition to the description.

A Glowing Experience

James_S, Jan 2023

This was our first Viator booking and our first tour in PR. It did not disappoint. We (group of about 30) were accompanied by 4 guides, and given a quick but useful tutorial for kayaking. As other reviewers commented, be prepared to kayak in the dark. It’s really a courtesy to all the other visitors and tour operators. All I can say is that it was entirely worth it, even with a couple collisions with mangrove branches on the way. Just understand that the bioluminescence depends on a variety of factors. (Do some research). We were happy with what we saw. A wholly unique experience!!!

Magical winter solstice on Biobay

Bridget_C, Dec 2022

Kayaking through the mangroves was so magical, stars were incredible, tarpon were jumping and our guide had great energy! She even shined her head lamp so we could catch a glimpse of an iguana in the trees. Seeing the glowing Microorganisms under the tarp was the best!

Amazing experience!! A must-do

William_E, Oct 2022

Such a fun excursion, our guide was incredible, the experience of kayaking through the mangroves to to biobay was fun and the bioluminescence was so cool and worth the money and effort to get there.

Pitch dark, cool, unique

Janice_M, Sep 2022

It was a new moon when we went so it was pitch black rowing through the mangroves which was an experience on its own. We floated for a bit in Laguna Grande and then headed back. When we put the oars or hands in the water it glowed. Super cool. Rowing back through the mangroves against the current was hard but our guide Rafael helped us. Very unique experience

Dariia_M, Aug 2022

Awesome experience! Must try activity in this area! We’ve really enjoyed kayaking at night, and bio glow!

Awesome Tour

NishanthNagesh_B, Dec 2021

Located perfectly at the entrance of the mangrove, saves you the effort of not having to kayak across strong currents. The tour was fun and informative, with the guides giving clear instructions to navigate through the mangroves.

Try it, you'll like it!

Mary_B, Dec 2021

Really cool experience, definitely recommend! Best time to visit is when their is a new moon! Loved our tour guide, spoke English real well too!

A solid experience!

Nick_R, Dec 2021

Really nice, fun, and knowledgeable guides who took us through the channel into the protected bay where we got to see the flagellates. They had a lot of great info, stories, and passion for the area that showed. Big props to Carlos for being funny and making the journey enjoyable.
