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.

La Parguera
La Parguera, a small fishing village in Lajas has reborn as a local and international destination. Because of its geographical location it offers one of the best preserved coral reef systems and mangrove forests in the Caribbean. Various restaurants and bars add to the local attractions. We will drive for about 2 hrs (bathroom stops offered along the way), as you enjoy the panoramic and lush views of the Central area that then changes to a semi-desert landscape. Upon arrival downtown we will stop for appetizers. 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.

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
, Nov 2021
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!

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

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!
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😞
