Puerto Rico is home to some incredibly beautiful beaches, but did you know that some of these beaches come completely alive after dark? That’s right! Imagine walking on a dark beach at night, where the only sound you can hear is from the waves crashing on the shore. When you look out into the darkness, you can see tiny little lights flickering atop the waves. The water is softly glowing, and it is a very peaceful and beautiful moment. Above you, the stars are twinkling like diamonds in the sky. As you go onto the water on your paddleboard, you see the glowing light around you with every stroke of your paddle. This is what it’s like to see bioluminescent Puerto Rico beaches at night – such an incredible experience!
Only a few places in the world have bioluminescent bays. Puerto Rico is lucky to have three: Laguna Grande in Fajardo, Mosquito Bay in Vieques, and La Parguera in Lajas. These bays are easily accessible from the different cities of Puerto Rico and are also close to the Port of San Juan.
Want to learn more about this once-in-a-lifetime experience? Keep reading! In this blog post, we’ll explore the best bioluminescent Puerto Rico beaches at night, when to visit, where to stay, and everything else you need to know to plan your trip.
What is Bioluminescence?
Bioluminescence is a natural phenomenon created by the production and emission of light made by various living organisms, including some species of bacteria, fungi, fish, and plankton. Bioluminescence happens when a chemical reaction occurs within the organisms, resulting in light emission.
Marine organisms, such as dinoflagellates and jellyfish, often use bioluminescence as a defense mechanism to deter predators and attract prey and mates. For example, some species of dinoflagellates can emit a bright blue-green light when agitated. But this defense mechanism is truly stunning to see!
One of the most famous bioluminescence phenomena is “glowing waves,” which can be seen in some coastal areas at night. This phenomenon is caused by the presence of large numbers of bioluminescent plankton in the water. These tiny organisms emit a bright blue light when the waves crash against the shore.
What is a Bioluminescent Bay?
Bioluminescent bays, also known as bio bays, are bodies of water such as lagoons, bays, or inlets that contain high concentrations of microorganisms called dinoflagellates (Pyrodinium bahamense). When these single-celled organisms are disturbed by movement or agitation in the water, they produce a glow-in-the-dark effect: bioluminescence!
When you paddle through or move the water, these tiny organisms produce a bright blue-green glow, appearing like billions of glowing stars lighting the water. Warmer water temperatures encourage the growth of dinoflagellates, intensifying the bioluminescent display.
Bioluminescent bays are found in different parts of the world, including Puerto Rico, Jamaica, Mexico, and Australia.
Bioluminescent bays attract visitors from all over the world who come to witness the stunning natural light show. Visitors can explore the bays by kayak, paddleboard, or boat and experience bioluminescence up close and personally. You can visit the best bioluminescent beaches on clear nights with little to no moonlight, as this will enhance the visibility of the bioluminescence.
Note that environmental factors and natural disasters can affect the bioluminescent bays. Hurricane Maria in 2017 affected Mosquito Bay, making it go dark. However, the dinoflagellates returned and brought back their signature glow. So, you should visit the bio bays soon because they might not last forever.
Why You Should Visit Bioluminescent Beaches in Puerto Rico at Night?
If you currently traveling in, or planning on going to Puerto Rico, visiting its bioluminescent bays is a must-do activity!
Puerto Rico’s beaches attract visitors with their natural beauty and crystal-clear waters, but they become even more magical at night. Puerto Rico’s bays are considered one of the island’s natural beauties, and for good reason. These bays are home to millions of dinoflagellates that create the eerie blue-green glow in the water when they are disturbed by movement.
In Puerto Rico, there are three Bio Bays: Mosquito Bay, Laguna Grande, and La Parguera.
El Yunque National Forest has two lagoons with Bio Bays: La Mina and La Coca.
You can explore these bays by taking a night kayaking tour or a boat trip. Paddle through the bioluminescent water and watch the glowing organisms as they light up the night. It is a fun and safe nighttime adventure that is perfect for all. You can also enjoy snorkeling and swimming. Many tours and activities are guided, so you don’t have to worry about getting lost or being in a dangerous situation.
But it’s not just about the beauty. These guided tours are a great opportunity to learn about marine life and the importance of ocean conservation. Your tour guides will provide information about the dinoflagellates, their role in the ecosystem, and how pollution can affect their survival.
With eco-friendly tours and fun nighttime adventures, there is no reason left not to visit the bioluminescent Puerto Rico beaches at night.
These are some of the BEST Bio Bay Tours in Puerto Rico I recommend:
When is the Best Time of Year to Visit Bioluminescent Bays in Puerto Rico?
The bioluminescent bays in Puerto Rico are open for visitors all year round. The best time to visit Puerto Rico bioluminescent bays is during the dry season, from December to mid-April. During this time, the weather is perfect, and you are most likely to see the bright glow of the dinoflagellates at their peak. You’ll also experience minimal rainfall during these months. Note that this is the peak tourist season in Puerto Rico, so you may encounter more crowds and higher prices for flights and accommodations.
The rainy season in Puerto Rico runs from June to November, which is not an ideal time to visit the bays. Heavy rainfall can cloud the water, making it difficult to see the glow from the dinoflagellates. There is also a higher risk of hurricanes, which can negatively impact the visibility of the bioluminescent bays.
Avoid visiting in mid-March when Spring Break travelers and college students flock to the island. Instead, consider visiting in February or April, when there are fewer crowds and more reasonable prices.
It is a good idea to check with your tour operator or the Department of Natural Resources to ensure optimal conditions for a bay tour.

What are the Best Conditions to Visit Bioluminescent Bays in Puerto Rico?
To see bioluminescence best, it must be really dark, with no light from the moon or other sources around. If there is a lot of light, like from the moon, you won’t see the glowing of the tiny organisms called Dinoflagellate plankton.
The best time of the month to visit the glowing beaches in Puerto Rico is during the moonless nights, two to three days before or after the new moon. During this moon phase, there is no natural light source. The dark sky provides the perfect backdrop for the glowing water. The dates for viewing the bioluminescence change each month.
Make sure to contact a reputable bioluminescence tour company to know their operating schedule before booking flights. There are about two weeks each month when you can see the bioluminescence the best. If a company says they can take you outside of these two weeks, they might be trying to scam you, so be careful.
Best Bioluminescent Puerto Rico Beaches at Night
Puerto Rico is home to 3 of the best bioluminescent beaches in the world!
Here is everything you need to know about visiting these natural wonders.
Mosquito Bay
Mosquito Bay, officially named Bahía Mosquito, is the most famous bioluminescent destination in Puerto Rico. It is located on the southern shore of Vieques Island. This natural wonder was recognized by the Guinness Book of World Records in 2006 as Puerto Rico’s brightest bioluminescent bay. The bay waters are filled with a high concentration of dinoflagellates, which inexplicably doubled in number after Hurricane Maria. These tiny organisms create a radiant display of neon-blue bioluminescence when disturbed.
With an average of 1,000,000 to 2,100,000 dinoflagellates per gallon of water, the bay’s pristine setting and lack of light pollution create a mesmerizing spectacle. The mangrove swamps that feed the plankton and the surrounding Natural Reserve of Mosquito Bay make it one of the best bioluminescent Puerto Rico Beaches at night.
Contrary to what the name might suggest, Mosquito Bay has nothing to do with the pesky insects. Instead, the bay is named after “El Mosquito,” a small vessel owned by Roberto Cofresí, a famous pirate who often hid his ship in the bioluminescent bay. This body of water was only connected to the ocean by a tiny inlet that was easily defendable.
Swimming is not allowed in Puerto Mosquito to preserve the delicate organisms, but you can dip your hands and feet in while kayaking. Moreover, you can also explore the mangrove forest during the day by joining a guided tour with tour companies.
How to Get to Mosquito Bay?
To reach Mosquito Bay from Puerto Rico, you have several options. First, you have to take a short ferry ride or flight to Vieques from the main island of Puerto Rico, San Juan.
The best way to reach Mosquito Bay is to fly from San Juan Airport to Vieques, which takes approximately 25 minutes. The Antonio Rivera Rodríguez Airport in Vieques is the primary entry point. From there, you can take a taxi, rent a car, or use local transportation to reach Mosquito Bay.
Another option is to take a ferry ride. Ferries depart from Ceiba on the east coast of Puerto Rico and take about 45 minutes to reach. You can reach the Ceiba terminal by taking a taxi or shuttle from San Juan and then take the ferry to the tiny island of Vieques. Some bioluminescent bay tour operators provide transportation once you reach the ferry terminal.
Note that there are no ferries late at night. Many visitors choose to stay overnight in Vieques before heading back.

Can I go to Bioluminescent Beaches in Puerto Rico at Night on my own?
Visiting the bioluminescent bays in Puerto Rico on your own can be challenging due to logistical reasons unless you have your own kayak and transportation. Even if you are a local with kayaking experience, I would not recommend it unless you are an advanced kayaker and know the area well. Therefore, most tourists prefer guided bioluminescence tours.
Can I visit bioluminescent beaches during a full moon?
You can visit Puerto Rico’s bio bays during a full moon, but the experience may be less vivid. For the best views, check moon phases and plan your visit during a new moon phase for minimal moonlight interference.
