Ryan was our operator and he was fantastic. This was such a special experience for our family with two littles under 5. They enjoyed the water so much. It was warm and calm waters. Bioluminescent was nothing like the pictures, but magical nonetheless. Stay close to the boat for the darkest shadow if you’re on the sunset tour as it creates the best area for viewing. Bring goggles or a snorkel for maximized viewing. Highly recommend this company for families.

(Prefiero notar mis experiencias y opiniones en inglés. ¡Grácias a Adriana y Fiol! Saludos desde Caguas y Baltimore!)
I’ve been overdue for a trip to Puerto Rico for many years, and especially given that my wife has never been here. I wanted to show her some of the natural wonders of where I came from. Neither of us has been to a bioluminescent bay. Well, at least I don’t remember seeing one when my parents would visit Fajardo.
Adriana and Fiol were warm and friendly tour guides and it’s obvious they could navigate La Parguera in their sleep. I recommend them highly and the charter they work for. Their familiarity with the water made it a comfortable and safe ride. And just remember to stay on “island time.” It might take a while to get out there, but things have to be in order before setting off.
Our first stop was near Cayo Caracoles (Snail Key) for a dip on warm meter-deep water, as we waited for the sun to set. Meanwhile, Fiol messed around with some in our group by feeding a small group of tarpon hanging out near all the tour boats also stopped nearby. :)
It wasn’t as dark out as we had hoped, but that’s beyond anyone’s control. There wasn’t a new moon and it had rained recently, so not all the plankton were on the surface, but still, my wife and I saw how the water sparkled as we got to swim and float in the bay. If we kicked our legs or used our arms to move around, we could see the glow around our limbs. We could also see the glow on any given boat’s wakes. It wasn’t as dramatic as we saw in YouTube videos, but that didn’t matter. It was all a sight to behold, and all under a star-filled sky. It was quite romantic.
Aside from the moon’s (our) timing and a minor mishap with my wife (she’s ok), this was an experience neither of us will forget. And we got to experience something in my Puerto Rico together for the first time.
¡Muchas grácias por todo y hasta la próxima vez…!

This was a unique and fun experience that should not be missed. My 9 year old son thought it was so cool. The water felt nice and the hosts were friendly and informative.

so much fun! don’t forget a towel or you’ll be cold. did the 9-11, it was shorter which i appreciated. captain ryan was great! my friend got stung by a jelly fish lol

The tour and guides were amazing! The experience was unlike anything I’ve ever experienced. Warm water, shooting stars, and bio luminescent glows that looked like stars in the water.
Note: Plan for 2.5 plus hours if you need to get dinner prior to your excursion. Reserva 304 is not the place to go unless you have 3 plus hours before your boat ride. The parking is a nightmare for dinner, use Calle to Avenue los Pescadores and park on the side streets. Even though the tour has parking… it is bumpy.

Very pleasant tour guides. Its a unique experience. We enjoyed it thoroughly and will recommend the tour

My husband and I took the sunset cruise tour. It was nice, but you can't see the sun actually set over the ocean. We then went into the bay where the bioluminescent algae live. We had to wait about 30 minutes for it to get dark enough to see (there was also no moon). Towards the end of our time there we saw "sparks" in the water. Prior to the sparks the glow looked more like cloudy water. The guide said on the 9pm and 11pm tours the algae is brighter. This was the main reason we came to Puerto Rico. If we were to do it again I think I'd get a hotel near this bay and come on the 9pm tour. Ryan our guide was great.

Our guides were great. They eased my fear of going into the water-especially at night. She had incredible knowledge of how the plankton interacts with the movement.
Crystal_L, Mar 2026
Unforgettable experience! My family of six all enjoyed the the bioluminescent very much. Our groups ages ranged from 12 to 46 years

Our Captain Ryan was friendly and professional. Experience was shorter than advertised but seemed like the right amount of time. 30 min boat ride to the bay, 30 mins to swim, 30 mins back to the dock. Make sure you bring towels!
Rebecca_H, Feb 2026
Swimming in the bioluminescent bay was an absolutely magical experience. We timed our trip with the new moon and the stars were just as breathtaking as the water. Ryan and Gabriel were great guides. It was honestly the most beautiful experience we’ve ever had, cannot recommend enough.
Jacob_B, Feb 2026
Experience alone was worth it, swimming with Tarpon, watching the sunset, then swimming in the bioluminescent bay. Incredible time!
Luke_W, Jan 2026
This experience was one for the books, the staff was amazing, knowledgeable, and really fun!!
The bio luminescence, swimming in it is a once in a life time experience 10/10 recommend.
Valerie_B, Jan 2026
Totally worth the drive from San Juan!!! The tour operators were so accommodating of our unexpected small problem and made sure we got the wonderful experience we expected. Can’t say enough good things about them and the natural wonder that bioluminescence is!
Laurie_L, Jan 2026
Loved being able to swim in the bioluminescence bay. Such a neat experience. Snorkeling/swimming around the little island before enjoying the sunset was neat. Would have been better with cocktails 😉
Eric_M, Nov 2025
Great sunset. Guide was very knowledgeable, Ryan was great.
Definitely try to go during February for peak bio time
Philip_M, Nov 2025
Pro tip: forget your phone and camera, and just be present in a fleeting moment. The Phytoplankton are camera shy, plus, you don’t want to be handling your phone in the dark in the water anyway.
Kelley_S, Oct 2025
One of the most magical experiences I’ve ever had . If you go, be sure to get in the water otherwise you don’t get the full effect
Alegdaly_V, Sep 2025
Great experience! Brian was a great captain, friendly and knowledgeable. My daughter and I really enjoyed ourselves ☺️
Kimberly_O, Jul 2025
Amazing beautiful experience. The kids enjoyed it to the max. Kids were 8 & 12 yrs old. I enjoyed it as well. So did my best friend
Christopher_J, Jul 2025
This biobay tour is the best way to experience the bioluminescent bay in La Parguera, Puerto Rico. Being able to swim in the bay, instead of just kayak in it or take a glass bottom boat, sets this tour apart.
The guides were knowledgeable, friendly, and professional. The boat was clean and well-maintained.
Highly recommend!
Nicole_R, Jun 2025
We had a great time! Our 3 and 5 year old had a blast as well. My five year old steered the boat for a bit and she loved it! The bio bay was so cool ! It doesn’t seem like much until you’re in it and then it’s magical. The tour guides were fantastic as well! Fun tour!
Katie_R, Jun 2025
Definitely bring towels and snorkel gear! At the sandbar you will snorkel with tarpon and in the bio bay you can get a close up glimpse of the sparkles under water!
Amy_S, Jun 2025
A one in a lifetime opportunity that everyone should experience! Ryan & Hector did an amazing job, too.
jacki_q, Jun 2025
Such an amazing experience- truly magical. Organized operation - felt safe and well informed, never felt rushed. This is truly something everyone should experience when coming to PR!
Christy_F, May 2025
This was a wonderful experience. Hector and Capt. Ferrell were excellent hosts. Don't hesitate to book this excursion. Even if you don't swim it's still an enjoyable experience that you will remember.
Yvelisse_P, May 2025
We had an amazing time with the captain and his mate and it was very safe and it was very beautiful and it was absolutely amazing you don't want to miss this experience!
Ashley_B, May 2025
Best experience we could ask for! Hector was a great guide and worked with us when we were having trouble getting to the site. Hector was very accommodating, funny, and nice! Strongly recommend this experience very one of a kind! Loved swimming with bioluminescence felt magical!
Kathy_D, May 2025
We had the BEST time!! Adriana and our boat Captain File were both fantastic. We enjoyed swimming with the Tarpon and of course the Biobay was simply amazing. Definitely one of the highlights from our vacation in PR. Don't pass up the opportunity to enjoy this experience.
