Night Kayaking and Bio Bay Tour

Witness the Beauty of Puerto Rico’s Laguna Grande on a Night Kayak Tour!

A truly unforgettable experience awaits,  paddle through the mangrove forest into the lagoon. Wave your paddle through the water in front of you and be mesmerized by the beauty of the night  and the tiny glowing specs of plankton or Dinoflagellates which are tiny unicellular marine plankton also known as fire plants.

Fajardo Bioluminescent Bay Kayak Tour Details

Meet for your Bioluminescent Bay Puerto Rico tours on the beach of Las Croabas, a small fishing village located on the extreme northeastern tip of the island.

Your bio bay tour guides will conduct a briefing session covering basic kayak handling, rules of the road, and how best to protect the pristine environment of the bioluminescent bay.

Then we launch our kayaks and head for a hidden opening in the mangroves at the northern end of the beach. Upon entering the mangroves, we follow a channel for a mile that leads to the Laguna Grande.

Leaving the channel and entering the lagoon by itself is a breathtaking experience! A wide expanse of gentle, rippling water surrounded by mangrove forests greets the adventurer, the mountains of the El Yunque Rainforest tower in the distance – profound tranquility envelopes all who enter!

But the best is yet to come! Your guides call the flotilla together for an informative talk about several topics: This unique ecosystem, the flora, fauna, and sea life that inhabits the lagoon, and historical notes of interest.

Discover the Fajardo Lighthouse, built by the Spanish in the 19th century, and of course, the incredible natural phenomenon that we’re here for – the shimmering glow of bioluminescence as you dip your paddles and glide through the sparkling water – an amazingly unique experience only found in few places on earth!

Attention!! About the Bioluminescent Bay:

• GLOW: Our bioluminescent bay is very delicate as it depends on the ecosystem that surrounds it. Due to climate changes the bioluminescent bay can reduce its fluorescent lights. This means that it will not always glow. This all depends on natural or human causes that can affect the organisms. Our company is not responsible for these changes as we do our best to provide a unique experience for all who visit the island, specifically Laguna Grande.
• ODOR: When mangrove plants drop their seeds, bacteria helps to breakdown the organic matter producing a sulphur reaction. This reaction creates sulphide gas which is known as the “rotten-egg smell”. Understanding that the smell is a natural phenomenon is important.                
• SARGASSUM: Is a type of seaweed:It’s a large group of brown algae that lives in the ocean. Sargassum can grow into dense mats of floating vegetation in tropical Atlantic waters. These floating mats provide food, refuge, and breeding grounds for many marine creatures, including turtles, fish, and crabs.
• Bioluminescence & Sargassum in the Bay: The glow in the Bio Bay is a natural phenomenon and the brightness of the glow can vary depending on environmental factors such as moonlight, rainfall, and water clarity. At times, floating mats of sargassum  may accumulate in the around the bay. While sargassum can change the appearance of the water surface and sometimes create a temporary barrier where the glow is less visible, it does not kill or eliminate the dinoflagellates. In many cases, the bioluminescence remains active and can still be seen when the water is stirred. For this reason, the presence of sargassum does not automatically mean the bay will not glow — but as with all natural events, visibility is never 100% guaranteed.

In simple terms:

Even if you see sargassum in the bay, the glow is often still there. It may look a little different, but the organisms that create the light remain active.
