A Core Memory Type of Experience - PLEASE DO THIS!! It was definitely the coolest thing we did during our Puerto Rico trip and even after driving two hours ourselves each way from where we were staying just for this, we loved it so much. Reading other reviews I knew this would be cool but it definitely still exceeded our expectations. Try going during a new moon!

Magical - Sunset at the cays, while treading the beach for 45 minutes. Then the biobay with hundreds (thousands) of stars and glowing water. The water is not just a little bit glowy - it’s noticeably fluorescent, feels like when you move in the water you have a superpower. The guide was friendly, outgoing and conversational when you talk to him, but respects the peace of the moment. The boat was in great shape.

Excellent Tour - We lucked out because we had Hector as our guide, and he was amazing! Spoke English and Spanish fluently and he was so easy to talk to. I would go on this tour 100 more times, it was that great. We did see the glow and the sparkles. Definitely worth the price, don't think about it, just book it.

Amazing second experience to bio bay! - This was our second visit to bio bay and our first with Maraeita charters! The captain and his first mate was awesome! Super knowledgeable and funny too!

Spectacular one of a kind experience! - Fior & Fiona were such wonderful hosts! Can’t say enough wonderful things about them. The whole experience was incredible. Definitely the coolest thing that we have done on the island! Why kayak, when you can swim with the dinoflagellates in the only place you can swim with them on the planet! Really special. A must do.

An Experience I Will Never Forget - The water was warm, the night sky was captivating, and the bioluminescence in the water was an unforgettable experience! We had a pretty small group (5 people total), and Ryan was a fantastic captain. Not only did he get us to the bay safely, he was extremely knowledgeable about the area and really good to talk to. He is also a certified lifeguard, so even if you can't swim, between the available floaties, life jackets, and his training, there is nothing to fear! I highly recommend this tour!

This is a must do! - What a great experience! Great weather and Captain Fiol handled the boat masterfully. My swimsuit sparkled and they gave us plenty of time to enjoy the bay. Linda gave us some history and made sure everyone had photos taken. Highly recommend this excursion!

Swimming under the stars in the Bioluminescent bay - 10/10 the bioluminescent bay is a must see, it was well worth the long drive. Swimming in glowing water under the stars is amazing.

One of our best experiences!! - This was such an amazing and magical experience for my family. Fiol and Linda were friendly, helpful, knowledgeable, and professional. Must do if you are looking for memorable and fascinating experience!

Great time - My friend and I had a great time. The location was easy to find and the instructions were clear. I was like a little kid in the water splashing around and honestly it was magical to see the blue across my fingers.
