Begin your evening excursion with pickup at your San Juan hotel. Board a tour vehicle with your small group of fellow adventurers and travel to La Parguera, a small fishing village in southwestern Puerto Rico. The bioluminescent bay located there is the only one in Puerto Rico that allows swimming and snorkeling. 

Arrive in La Parguera and listen to a short introduction to the natural phenomenon by your local guide. 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.

Watch the sunset as we head out for a 25 minute ride thru the mangrove channels. You will have the opportunity to swim at one of it's cays, before we head out to the area where the bioluminescence happens. Your guide will explain everything you need to know about these microscopic dinoflagelates that give off heat in the form of light when disturbed. Once we reach the bay you will have the opportunity to swim (optional) and experience this phenomenon first hand.

Excellent Excursion
, Jun 2022
La Parguera Glowing Bioluminescent Bay Boat Tour from San Juan This was an 8 hour excursion that included a 2.5 hour ride each way to a small fishing town where we had a delicious dinner in the midst of an outdoor day party. Then we took a boat ride to a spot where we joined dozens of other boats that were anchored in 4-5 ft deep water. Music was playing from every boat and people partying and dancing on the boats and in the water. So we jumped in too! I've never experienced anything like it. Finally as it got dark we moved on to the bioluminescent bay and several jumped in to disturb the waters so we could see the sparkles. We also got an astronomical show using the skyview app on our cell phones. Julian and Hector were fantastic and the excursion was a highlight of our vacation! Well worth the money.
Like swimming in glitter
, May 2022
Had some reservations about going with 2 toddlers, as it's a long drive each way. In the end, it was fine. There was no bathroom stops, that was difficult, as I thought my bladder might rupture for the last hour. When we arrived, I really wanted to spend a minute exploring the little area, but that didn't happen either... BUT... The experience was so amazing, it was all completely worth it. It was like swimming in moving glitter. It is hard to explain, but a MUST SEE at least once in this lifetime. Definitely go when there is no moon, it made it so much brighter. Hector, the captain, is funny, and has a plethora of knowledge. I say... GO!
Worth every penny and the long drive from San Juan!
, Apr 2022
Although the ride was a long one from San Juan, it was absolutely worth it. We had good food when we arrived and then headed out on the boat. We watched the sunset from in the water on a rather raucous sandbar (there were about a dozen boats there doing the same and playing music) before heading to the bay. Puerto Rico has 3 out of the 5 bays in the world with enough dinoflagellates to be classified as a bioluminescent bay and this is the only one in Puerto Rico in which you can swim. The experience was absolutely magnificent - a true once in a lifetime experience! I was glad to have read in another review that the bioluminescence didn’t look like the picture shown in the ad for the tour so I knew what to expect - it is like green glowing glitter in the water. That description does not adequately capture the experience…it really is extraordinary. I wish I had thought to bring a pair of goggles to look at the bioluminescence more clearly underwater, but that is all. This was a great excursion with a teenager.
They never showed up to...
, Mar 2022
They never showed up to pick us up, and then blamed me for booking it “last minute” —but had no issue with taking my money and sending confirmation. Then I looked at all the other reviews and no-shows seem to be the norm for this tour. Stay away from this one!
Unfortunately this tour...
, Mar 2022
Unfortunately this tour cancelled and it shifted (completely ruined) our trip because we could not book anything else as everything is all booked. Very stressful consequence

Enjoyed it
, Mar 2022
Guides were great. Boat ride to bioluminescence was about 15-20 min on boat. It’s not super bright like you see in pictures but the experience itself is cool.
What excursion?!!?
, Mar 2022
After booking a hotel specifically for this excursion at an added $400 expense. I received a call 6pm from them the night before cancelling my trip!! They have flooded my email with their garbage of amazing excisions and managed to send me a review not even knowing YOU CANCELLED ME—-NEWSFLASH, no word yet about my REFUND OF $480+ dollars!! I want my money back and for you to remove me from your mailing list.

Five stars! Friendly tour guide. The whole evening was run smoothly and professionally. This is an amazing one of a kind experience. The extra stop off to swim through the mangrove was wonderful bonus!
Highly recommend

One of a kind experience seeing the bioluminescence. Truly remarkable. Comfortable ride to and from San Juan.

We are glad you gave yourselves the opportunity to explore an attraction farther from the Metropolitan area and enjoyed it all! This is truly a unique and memorable experience.
Recommend “must do” when in Puerto Rico!

Great way to see much of puerto rico
, Dec 2021
We enjoyed the trip avoid as much moonlight as possible. We were at half crescent and it was probably too much. The staff were great. Great drive through the countryside. Loved the small community plaza was so cool. It is a good 2.5 hour drive but through much of the island so you see lots of different areas.
Great experience!
, Dec 2021
We had a great time and felt very safe. Our guide even took extra care to make sure we all got back to our hotels and condos safely since we got back to the city late in the evening.

Not worth it!
, Nov 2021
Wasn't worth the money or the 2 hour drive. Really we saw nothing! I feel like it was false advertising and I considered asking for a refund. Im still considering it.

Unique, wonderful experience

A fantastic, unique experience. A long drive from San Juan but so worth it. Something you can only experience here.

Bioluminescence is like running your hands through the stars or stirring them up with your legs. We both LOVED it!!! Bucket list for sure!
Amazing experience!
, Nov 2021
Can’t say enough good things about our driver Harold! He was a great tour guide and made the long trip from San Juan so much fun. Hector was our boat captain and also did a great job explaining everything. Seeing the bay light up with twinkling stars was a one of a kind experience! You get tacos for dinner and they are delicious but bring snacks because it’s a long ride there and back!
Great Fun
, Oct 2021
Julian our tour guide and driver were amazingly fun . Hotel pick up was right on time in a very comfortable Mercedes Van with coolers filled with beers and waters that are offered the second you get into van . Our guides arranged a good dinner that we ate after our swim in the Caribbean Sea and bio bay. Captain Hector, was very informative, nice boat also stocked with plenty of beer, soda and waters. The glowing water in the bay were so beautiful!!! It looked like sparklers on the water… BRING GOGGLES IT ENHANCES YOUR Experience 100%!!!! I highly recommend this tour and Please don’t forget to tip your guides they totally deserve it!! Can’t wait to do it again!!!
Fireflies in the ocean

The tour guides where so much fun. The experience was fun, adventurous . Julian and Harold turned the bus into a karaoke machine.
Picture is misleading,...

Picture is misleading, but still an awesome time! Looked like little fireflies in the water. So cool!
