The bioluminescent bay located there is the only one in Puerto Rico that allows swimming and snorkeling.

After the sun sets, board a boat for the 25-minute ride through the mangrove swamps to the bioluminescent bay. Once you reach the bay, you will have the opportunity to swim. Your swimming disturbs the glowing dinoflagellates, microscopic creatures that give off a glowing light, creating an otherworldly effect. Spend 30 to 45 minutes marveling at this strange, lovely light show before heading back to the tour center. 

Board your transportation back to San Juan for hotel drop-off.

Picture is misleading,...
, Oct 2021
Picture is misleading, but still an awesome time! Looked like little fireflies in the water. So cool!
Not worth it
, Sep 2021
Our original tour was canceled because not enough people signed up, we got routed to this company's kayak tour instead. Bus was okay, but very boring. No history or energy, as well as no official plans. No true bathroom was established when we arrived to the destination and had to rough it in the very smelly public park bathroom. Tour guides were experienced, but seemed uninterested. Felt like the tour was ran by frat guys. The ride out was very rough. Once we arrived at the bay, it was very hard to see the glow, nothing like the pictures. The ride back felt dangerous as it was dark and other groups didn't have lights on the boat. Overall very intense and underwhelming. We saw bad reviews, but figured it was worth the try. However; my warning to you all is to not go.
Not worth time and cost
, Sep 2021
Drive through the middle of the state from end to other was great. Our guide was really good and informative and brought us back safely Did not have the same experience as shown on the website for 8 hours.
Beautiful to experience but I think it would beneficial to have a step stool to step in the van esp for us older adults.

Listening to rap music for 5 hrs round trip! Was inconsiderate and it was suppose to be an English speaking tour music should had been in English more suited to the passengers. Did not enjoy that at all😞
Bioluminescence tour
, Aug 2021
It was an amazing experience that pictures can not show! It looked like pixie dust off your fingers. Our guide and boat captain were very detailed and had tons of drinks and food available. I would highly recommend this trip for a once in a lifetime experience!
Magical experience! Hector and Felix were awesome!!
, Aug 2021
We loved everything about the trip and would highly recommend it to everyone! Felix was the best driver/tourguide/host we've ever met. He was funny, enthusiastic and knowledgeable about the destination. We also met Hector, the captain, who was friendly and hilarious. Together, Hector and Felix took care of us throughout the trip, found the best spots for us to swim in and made sure we were having fun the whole time. We never felt being rushed being underwater and playing with the bioluminescence (which was so magical!). It was a wonderfully smooth and enjoyable experience that we will never forget!
Highly recommend
, Aug 2021
It’s was an awesome experience. You’re not able to catch anything on camera but the memories will always last. Hector, he was our Captain, he sang a little bit, educated us, he was awesome. Our tour guide Felix, he was by far the best person I’ve encountered. He made all of us feel like a real family. Pointed things out while driving to the bay. We laughed, danced, explored. It was truly amazing. I would totally do this again with the same people! (Bring goggles for an even better sight)
A magical experience!
, Aug 2021
The bio bay was a really magical experience! I felt very powerful with stars shooting out of my fingers! And the sky was full of stars! Before the bio bay, we went on a nice swim and a kind of party area that was fun. The temperature of the water was perfect. It was so much fun I would definitely do it again and I highly recommend it!
Canceled Due to Tropical Storm
, Aug 2021
There was a tropical storm in Puerto Rico that day, and our trip was canceled. The guide told me that I could either reschedule or get a refund; I was leaving on their next tour date. I requested a refund, and am waiting for my refund....$211 was paid...They canceled at 10:15 am, I was driving, and got caught driving in the storm, in both directions. I am a native New Yorker...I can now say that my tour, was driving in a tropical checked.
Nice activity
, Aug 2021
Our guide Felix was great. Super friendly! The bioluminescent water was fun! Do not expect to see what you see in pictures though! A good description was tinker bell. You have to be in the water to really see it. I would not say it’s incredible but I’m glad I did it. The Mercedes van was pretty comfortable. Good AC. Felix was great in that he let an extra large passenger sit in the front.
