Enjoy a sunset cruise followed by an exploration of one of Puerto Rico’s bioluminescent bays during this full-day excursion from San Juan. Experience the glowing rays of the sun as they fade into the ocean. Then see a different type of glowing as you explore and swim in the bioluminescent waters near the town La Parguera.
  • Enjoy a combination sunset cruise and bioluminescent bay boat tour
  • Watch the last rays of light melt into the ocean
  • Explore the amazing glowing waters of a bioluminescent bay near La Parguera
  • Discover two of Puerto Rico's most scenic coastal sights on a single trip
Receive an afternoon pickup from your San Juan hotel and head south to the coastal town of La Parguera, about 2-hours away. As you drive you’ll enjoy the views of the Puerto Rican countryside.

When you arrive in this seaside city, board a boat for your evening experience on the water. Motor out to one of the scenic ‘cays’ (islands) located just offshore to watch the sun slip into the ocean.

As the sky grows dark, continue to a nearby bioluminescent bay, watching in wonder as the water emits an eerie blue-like glow. It’s a sight that can only be seen in a handful of locations around the world. Then, slip into the glowing waters for a swim before you return to port for the drive back to San Juan and a drop-off at your hotel.

Friendly Guide, Great Experience
, Aug 2019
My girlfriend and I chose this tour because this is the one Bio Bay where you can go swimming, rather than just kayaking through the water. It did not disappoint. Being able to swim in the water made this experience. The bioluminescent microorganisms that create the light glow when you disturb them. You can do more of that swimming than with a kayak paddle. Also, don't expect it to look like the pictures. Or to be able to take pictures, unless you're familiar with low-light photography techniques. It's not all about the pictures though. Enjoy the experience because it's pretty magical. Our guide was also friendly and full of knowledge about Puerto Rico, the towns we drove through, and the Bio Bay. He made sure we had fun and were comfortable.
A million stars in the water

Wow! What an amazing experience this was. We were a group of 7 and were picked up from our rental home. They did manage to cram 5 more people in the van, so it was a pretty tight fit, and the AC int the back of the van didn’t work well at all until we were out of San Juan and moving quickly on the freeway. Our guide Steve was very informative about the local sights we passed, but sadly in the back two rows, we couldn’t hear anything at all. Luckily my brother was sitting in the front seat and provided us with a running text list of everything he was saying. He stopped once at a gas station so we could pee, upon request. Upon arriving at the dock, we were taken to a restaurant to enjoy our tacos (which he ordered while we used the facilities at our previous stop) The fish ones were great, but chicken was not a win according to everyone who ordered them. Then we had about 20 mins to run around and look at the shops (mostly jewelry- no shirts that I saw) buy one more drink, and hop on the boats. Happily they split our group of 12 into 2 boats so we got our own with just us 7. The first stop was a beautiful mangrove Island that we got to run around and explore (they had some OFF for us to use on request since we hadn’t thought to bring any, but bring some! You need it at sundown for sure!) and then after the sun set we went out into the bay and set anchor and swam for plenty of time. We went 3 days before a new moon and it was pretty dark but not pitch black. It rained pretty heavily on us as we went out (they let us store our dry stuff in a hatch) but it cleared up just as we parked. At first I was disappointed as we drove in because there was not a glowing blue trail behind us or anything that you could see from the boat, but once you jumped in the water (totally warm) and your eyes adjusted you could see the millions of sparkles, glittering like diamonds in the black water. I ran up to get my goggles and if you ducked your head under and moved your arms in front of you, it was like fireflies in the water. They passed out pool noodles if you needed or wanted one and everyone felt safe and secure. The best was to position yourself about 10-15 feet from everyone else and not move for a minute and then swoosh your hands through the water- it was so magical:) A quick (and chilly) boat ride back to the dock and we were allowed to dry off and change (and pee!) and then we started the long trek back. Almost everyone fell asleep so it wasn’t too miserable. I would say a neck pillow would not be remiss... lol Steve was super friendly and polite and we enjoyed him thoroughly.
Needs to be more transparent

This was a surprisingly long drive etc. and the guides were never up front about what exactly we would do, what facilities would be available - what can be done if someone is not comfortable swimming. The car was uncomfortable. I asked for a life vest and was told I would get one at the bay - I did not. Also - not safe if someone is saying they are not a good swimmer - there are no 100% guarantees. The guides were not engaging about what is happening in the bay. I think the best way to see this would be staying overnight if the drives are 3 + hours.

Hi Alysaia! I completely agreed with you, needs to be more transparent. First you called at last minute and I found you and your husband a space for the same day. I explained the 2 hour driving (I verified the GPS, 2:13 including the bathroom stop at Penuelas city) and I told you we have available life vest and noodles. I told you was a festival at La Parguera and will be pack. I explain you by phone the whole tour before you gave me your credit card number. The tour guide called as soon the group arrived at dock. He told me about your attitude and you refuse to swim because, as you wrote, you are not a good swimmer. You refuse to use the life vest because was dark. I spoke with the captain and he explained how rude you was at boat. Also I called the other 2 couples and they felt uncomfortable because you have an attitude and spoke and complain loud. We work really hard for exceed all our guest expectations, reviews speak for us. As you wrote is no 100% guarantees and you are right, you are in the 1% unpleased. We pride are selves for being honest and explain all details about the tour and you as a customer are not, you made all of the rest of the uncomfortable. Maybe private tours are your best option.

Stunningly beautiful! Best day in PR!

If you can only do one thing in Puerto Rico, this should be it! The guides, boat captain, and tour company owner were all super friendly and knowledgeable. There was a surprise stop at a mangrove to swim in the clear water and walk around. And the bay!! I won't even try to describe it, because it's not possible. Magical experience with the luminous water and the bright stars overhead. We also did a glass bottom kayak tour in anther bay but swimming in La Parguera was so much more incredible!

I cannot say enough wonderful things about this tour, from start to finish. Robert and Glenda picked us up at out hotel right when they said they would and we drove south through the island. There were so many different things to see along the way and the guides were helpful in explaining things and answering our touristy questions! We got to this cute little town , had dinner, and then headed out on the boat. We had a short stop at a small island to watch the sunset and then out to the bio bay after dark. As we entered the bay you could see fish swimming with trails of glittery gold behind them. Amazing, and even better when you enter the water to swim! This whole experience was nothing short of magical and it was worth every penny! If you are in Puerto Rico then this is a must!

The trip was absolutely amazing! One of the coolest experiences I have ever encountered!! The one and only downfall is the trip is far from San Juan ~2.5-3 hours away in a van that has no neck support. Even with that being said I would still go back :)

This tour was not what we expected from reading the internet write up. The bus pickup was late and the two hour ride was very rough. It did includes tacos that were good. It doesn't mention swimming or needing a towel so we weren't prepared. The boat seats were wet and the boat driver was miffed that we didn't have towels to wipe down his seats. Drinks were offered but no bathroom was available. A sunset was part of the tour, we were unable to see it because they tethered our boat to another boat that blocked our view. The bioluminescence was not blue as in the picture, it was just looked like white effervescent water. You can't even take pictures unless you have a 6000 camera according to the boat driver. We were very disappointed and it's waste of time.

One of the few companies willing to take us out this night. The bay is brighter on certain moon cycles. But we were so greatful to have the experience and it was bright enough to see the illumination. The kayak ride through the dark canal was really cool as well.

Pros - A once in a lifetime experience!! I feel very fortunate to have swam in the Bio Bay. Definitely bring a suit and towel. You will regret it if you don't get it the water. Also, there is a bathroom you can use to change into dry clothes for the ride home. Cons - I would have liked more timely communication regarding pick up time. I also thought there was a lot of waiting in Parguera...both before and after the tour. Other - The glow looks similar to sprinkled silver glitter.
