Description

Discover the Magic of Bioluminescence in Fajardo's Laguna Grande!

Kayaking through Fajardo’s Laguna Grande is like stepping into another world. This special bay is home to microscopic organisms that make the water glow with movement, lighting up the night in a way that feels almost otherworldly. As you paddle, you’ll leave trails of light in the water, and fish darting below the surface will create sparkling bursts of brilliance. It’s an unforgettable sight that can only be found in a handful of places on Earth, and Fajardo’s bay is one of the best.
The tour begins at Las Croabas, where you’ll get a quick lesson in kayaking and safety before heading into the mangrove channel. The entrance to the bio bay winds through a tunnel of red mangroves that are part of the Las Cabezas de San Juan Nature Reserve. Along the way, your guide will point out unique plants and animals that call this ecosystem home. As the sky darkens, the peaceful sounds of nature and the soft glow of the evening set the perfect tone for what’s to come.
When you reach the lagoon, the bioluminescence comes to life. With every paddle stroke, the water lights up around you, creating glowing swirls and patterns. Tiny fish seem to shimmer as they dart through the bay, adding to the magical display. Depending on the moon phase, the glow might be subtle or bright, but it’s always visible and always amazing. As the night deepens, you’ll head back through the mangrove channel, surrounded by the sounds of the forest and the night sky overhead. It’s an adventure that leaves you with incredible memories and a story to tell for years to come.

Participants exceeding the combined or individual weight capacity will not be allowed to participate, and no refunds will be issued. Please inform each person from your party.
  • The following guests cannot participate: Pregnant women, guests with recent surgeries, guests with neck, back, arm or leg problems or casts, and guests who have epilepsy, heart conditions and/or dizziness.

  • Depending on the season, it is possible to find large amounts of sargassum (floating algae) during the tour; this is also a natural phenomenon, but it can become uncomfortable.

FAQs

What should I wear?

Wear comfortable clothes that can get wet, and bring water shoes.

What if the weather is bad?

The tour operates rain or shine, but in the event of unsafe conditions, KPR Operations Team will cancel and offer rescheduling or a refund.

Do I need experience to kayak?

A moderate skill level is required, but pre-tour training is provided.

Can I bring a camera?

Bioluminescence is almost impossible to capture with regular cameras. Plus, everything in your kayak will get wet. We strongly recommend you be careful with your camera.

If you still want to bring a camera, make sure that it is waterproof. We also recommend that you use a leash to attach it to your life vest. Do not expose expensive and DSLR cameras to futile risks. The place will be completely dark. Diving in the lagoon is prohibited. If anything falls in the water, it will be impossible to recover.

Kayaking Trip Puerto Rico gives free photos if the equipment works. We’ll upload your photos and offer you links to download your favorites. As a thank you for choosing us as your Puerto Rico operators these images are free.

Notes: Please allow 5-7 days for the link to be sent to you via email. If you would rather not have your photo taken no problem, please just notify your guides at the beginning of each excursion.

Why is swimming not allowed in the Bioluminescent Bay?

There are several reasons why swimming is not allowed in the Bioluminescent Bay. Most of them have to do with ecological impact and safety:

  • To keep the waters clear and free of sedimentation. The organism that produces the bioluminescence — Pyrodinium bahamense— needs clear waters to complete the process of photosynthesis during daylight hours. If groups of people jump into the water, they will stir up the sediments from the bottom of the lagoon, making the water murky, which hinders photosynthesis and threatens the life of these glowing organisms.
  • To keep the lagoon free of pollutants. Deodorants, hair gels, skin lotions, perfumes, insect repellents containing DEET, and other personal care products contain chemicals that directly affect the bioluminescent organisms of the bay.

I don’t know how to swim. Can I still go?

Of course! First, we will not be swimming on this tour. All our guests will be provided with USCG approved life vest, and it is mandatory for you to wear it while kayaking. We will be paddling through calm, protected waters, and all of our kayaks are very stable. Even if, for any reason, you do fall in, the water depth throughout the mangrove channel (where you will be kayaking most of the way) is 3 to 4 ft (0.9 to 1.2 m) deep.

Is it easy to get in and out of the kayaks?

You will board your kayak on easily accessible, shallow waters. If you need help getting on and off the kayak, our staff will gladly assist you. Your guide will begin the tour with a short orientation on the basics of kayaking, from getting in the kayak to rowing properly.

Is food included in the tour?

Our Bio Bay excursion includes SNACKS: (water, fruits, and granola bars.) However, these are not intended as dinner. We recommend you have dinner before or after the trip. There are plenty of restaurants, food trucks, and kiosks in the Las Croabas area, some of them at walking distance from Kayaking Puerto Rico’s tent and tour departure site.

Where can I learn more about bioluminescence?

Check out our blog describing bioluminescence more in depth at Bioluminescence Kayaking!

How hard is it to kayak in the Bio Bay?

This is a beginner friendly kayaking spot! The lagoon and mangrove tunnels are very calm and a great place to try kayaking for the first time.

If you are looking for more information on beginner kayaking, check out TripOutside’s blog post on Kayaking for Beginners!

When is the best time to see the bioluminescence?

The bioluminescent intensity depends on weather conditions such as rain, tide, moon phase, sunlight and many other natural factors out of our control. Ideally, the best time to visit is around the new moon and during the dry months, December to March with a midsummer dry season June to July.
