An Ultimate Guide to Puerto Ricos Bioluminescent Bays

There are only five bioluminescent bays around the world, with Vieques’ being the brightest and most magical. Swimming is not allowed in Mosquito Bay and Laguna Grande; you can swim and snorkel in the bay at La Parguera. Remember to plan and book your tour around the moon cycle, the darker the night, the brighter the bioluminescence. You’ll just be limited to using a tripod on the side of the bay and hope that it’s either raining or that you have a good zoom lens and can see people on a tour kayaking.

The brightest areas are often the waters surrounded by groves of red mangrove trees, as their leaves provide the perfect nutrient-rich habitat for these plankton to grow. You will need to stay overnight as neither ferries or planes will be departing from the island after the tour is finished, late at night. I also stayed near the Malecon, which was the meeting area for the shuttle to and from the kayaking experience, included in the price of the tour. I walked to the Malecon, otherwise I used a taxi to get to and from the hotel and the airport.

As soon as it’s dark if you move your arms in the water you will see spectacular streams of glow in the water provoked by your body movement. The water is also very warm and you just want to stay there all night and play with this bioluminescence. Especially in the moonlight, it’s an amazing off-the-beaten-path experience that you must include in your list of the things to do in Cancun. If you do visit Laguna Grande, understand that you will not have an intimate bioluminescent kayaking experience — numerous tours go out at once and you will share the bio bay with many others. To be completely honest, I would only visit if you’re looking for a quick excursion from San Juan. The heavy tourism is affecting the bio bay and the bioluminescence is noticeably less bright.

Kumbalangi is located in the Ernakulam district close to Cochin, Kerala. It is considered India’s first eco-friendly tourist island village. The people of the village make a living through fishing and tourism. The Chinese nets used for fishing are a popular tourist attraction here. This is one of the best places in India to indulge in typical village life. While the phenomenon might look like some kind of alien creation, it is actually caused by something a lot less harmless.

You may have seen the magical wonder of bioluminescence in movies such as Avatar, Nim’s Island, and Life of Pi. You can even head to Disney World to be immersed in a world of bioluminescence, but in Puerto Rico, you can experience the REAL magic. On the southwestern coast of the island, you can visit La Parguera Bay, near Lajas, the only bioluminescent bay in Puerto Rico where you’ll be allowed to swim and dive.

This bay is often referred to as “magical”, those blessed with the opportunity to experience it always agree. The bioluminescent bay in Vieques was officially declared the brightest in the world by Guinness Book of World Records in 2008. Hurricane Maria caused much destruction on the island, it sadly disrupted the delicate ley abroad travel and lifestyle blog balance of the bay, the beloved Mosquito Bay went dark. To everyone’s surprise the bioluminescent bay not only recovered, but it is also brighter than it ever was in the past. Since then, the ecosystems are recovering, and hurricanes can also have a positive influence on the number of dinoflagellates in the water.

Depending on which bio bay you visit — Laguna Grande, Mosquito Bay, or La Parguera — you can enjoy snorkeling, kayaking, and even swimming among the bioluminescence. Mosquito Bay is located on the island of Vieques, east of the coast of Puerto Rico. Mosquito Bay is the brightest and best-known bioluminescent bay in the world. Recognized in 2006 by the Guinness World Records as the brightest bio bay in the world. The bay is said to have one of the highest concentrations of the plankton in the world, ranging from an average of 700,000 bioluminescent dinoflagellates to 2,100,000 per gallon of water.

If you’re short on time, fly directly from San Juan to Vieques for the Vieques bio bay tour. We’ve flown and taken the ferry both and would definitely recommend flying. The flight is less stress and offers beautiful views along the way. However, if you find you have more time and don’t want to spend the money on a flight, the ferry is another good option to get from Ceiba to Vieques and then start your Vieques bioluminescent bay tour. If you’re looking for the bioluminescent bay San Juan, there isn’t bioluminescent water in the city itself, but Laguna Grande, Fajardo is only a short distance away and is therefore one of the most visited spots.
