Such a great experience! The tour staff went above and beyond to make it even better. I wanted to give my special thanks to Enrique and Amary for their support and help during the tour. They make sure everyone gets to the lagoon safe and sound. They were also super fun! I would definitely choose them again if i come back to the island again

Glow in the dark glitter

Shar_G, Apr 2024

So memorable and a truly unique experience! Lived up to all my expectations and more. Want to give special shout out to Javier who helped us with kayaking as we were novice kayakers. But we made it out without capsizing , so I’d say a success! The bioluminescent was so surreal. Felt like we were in Avatar. They looked like glitter!

Awesome!

Tiffany_L, Apr 2024

Excellent! The guides (Javier, Enrique and Natalie perhaps??) were excellent. It was easy kayaking and the bioluminesce was truly awesome! Kids and adults alike loved it. We want to go back again tonight!! Best part of the trip by far.

Magical journey

Marianne_B, Apr 2024

Awesome bio tour

Cinthia_P, Apr 2024

We did the bio bay tour in Fajardo with Pure Adventure. It was awesome! We lucked out with great weather and the bio illumination that night was brilliant. The team was Informative, educational, and entertaining. They were also very patient and understanding with my 7yo and I who were using a kayak for the very first time. Natalia, Javier, Amaury, and Enrique at Pure Adventure were all amazing!

Response from Host, Apr 2024

Dear Cinthia_P, Thank you so much for your magnificent comment. We really appreciate it. You and your kid did a fantastic job! We hope to see you again. Cordially, PURE ADVENTURE’S TEAM

Great experience but very crowded. Too many kayaks

prashanth_p, Apr 2024

The bioluminescence was wonderful. we had a good experience but there were too many people too crowded and kayaking was difficult Because there was 2 way traffic . the guides were helpful in getting us back, but instructions could have been better during the kayaking

Response from Host, Apr 2024

Hello prashanth_p, Thank you for your feedback. We are sorry to hear that your expectations were not met. As of now, we are during high season. This means that the area gets very crowded, as stated in our website. Unfortunately, we can’t control the flow of people since other companies operate in the area. However, we make sure to keep our group safe since safety is our priority. Thank you again for your feedback. Cordially, Yolanda Ramos PURE ADVENTURE

Staff was incredible. As...

Theda_R, Apr 2024

Staff was incredible. As we had a few issues getting the hang of the rowing they were there to help us out and we always felt safe and confident. The flip side we barely saw the bioluminescent creatures. NO MOON

Good time and a few tips

William_S, Apr 2024

It was a fun tour overall, but here are some tips. 1. You will get wet just by paddling the kayak so be prepared. I would not wear anything nice. 2. It's dark, especially on the way back, and we took the 6 PM (probably actually left at 6:30) tour. 3. Don't try and pass other kayaks. Just listen to the guides...it's really not that hard but of course you have people doing it so be ready for them to bang into your kayak. That part is just annoying, but you won't tip. Once out in the bay, just have fun. They try explaining some of the constellations, but I ignored that and just have your hand or leg moving in the water to enjoy the lights, since that's what you are there for (Probably 20-25 minutes in the Bay). Enjoy!

Beautifully unique experience...great for families!

LaTanya_S, Apr 2024

Our party of inexperienced kayakers consisted of 2 parents and 2 teenage girls and we thoroughly enjoyed the Bio Bay tour! Our guides of Natalia, Enrique, Javier, Amaury and Catalina kept a close eye on us to make sure we were comfortable. The information shared on the phytoplankton was very interesting and we learned a lot. It is so beautiful and to know that Puerto Rico has 3 of the 5 bays in the world makes it a special activity. We were able to see a lot of the glow due to the complete darkness of the area. Pure Adventures was easy to communicate with before our tour to arrange transportation. We would absolutely use them again!

Response from Host, Apr 2024

Hi LaTanya_S, Thank you very very much for your wonderful feedback. It was a pleasure to serve you and to share this beautiful place with you. We hope to see you again soon. Cordially, PURE ADVENTURE’S TEAM

Spectacular sunset tour!

Adrienne_H, Apr 2024

Amazing experience, excellent guides, beautiful scenery. I had heard from a friend who went on a similar kayak experience a few months ago (clearly with a different tour company) that it was super crowded and her tour guide was so far ahead they could not hear anything he said. We had the exact opposite experience. There was plenty of room in the canal for all the kayaks in our group and there was an ample number of guides to provide adequate support in front middle and back. When someone fell out of their kayak Natalya (one of the guides) was there within a few seconds to help them out. Natalya also gave us an amazing presentation on the stars that were shining that night. This was definitely one of the highlights of our wonderful trip to PR. Highly recommend it!

We had a perfect night with great conditions. The ride through the mangrove was fun and easy to navigate. We especially enjoyed the light show in the water on the way back

Had a great time-tour...

Reena_S, Apr 2024

Had a great time-tour guides were wonderful! They were patient with my daughter and I who were beginners who kept getting stuck! We had a great night!

Response from Host, Apr 2024

Hey Reena_S, It seems like you explore the mangrove very closely ;)) Thank you so much for coming with us. We are really happy that you and your daughter had a wonderful time. We hope to see you again soon. Cordially, Yolanda Ramos PURE ADVENTURE

Awesome adventure

Brandy_C, Apr 2024

Family of four with two teens (13 & 15). Loved leaving just after 6:00 PM to see where we were paddling and then pitch black upon return. The crew was friendly, informative, and made our experience memorable. The bioluminescence was spectacular! So cool to work for the experience instead of just seeing it from a typical tourist boat trip.

Response from Host, Apr 2024

Hello Brandy_C, Thank you so much for joining us and for sharing your feedback, we truly appreciate it. I am so glad that you and your family has an excellent time with us. You chose the perfect timing to visit the Bio Bay, sunset time ;) We hope to see you again in the future. Cordially, Yolanda Ramos PURE ADVENTURE

Just OK - not a must do.

Amy_C, Apr 2024

Our family of four thought the Bio Bay Kayak tour was average at best. The staff was a bit rude and could’ve done a better job spreading out amongst the group. If you are anxious about the dark at all, this not for you. The bio bay water is cool but only amounts to about 10 minutes of a 2 hr paddle. Having kayaked before would be helpful-we all had. It is a lot of money for what you experience. It is not a must do in Puerto Rico.

Response from Host, Apr 2024

Hello Amy_C, Thank you for your feedback. We are sorry to hear that our tour did not meet your expectations. At Pure Adventure, safety is the highest priority. Because of this, rules are enforced seriously. This may come off as rude, which is not the intention, but safety is first. Again, thank you for your feedback. Cordially, Yolanda Ramos PURE ADVENTURE

Great tour!
