About
- One of the most spectacular sights on a night trip in Caribbean waters is to witness hundreds of tiny star-like bioluminescent plankton scintillating like a starry sky as you move through the dark water. Wave your paddle through the water in front of you, and be mesmerized by the tiny glowing specs of plankton or Dinoflagellates which are tiny unicellular marine plankton also known as fire plants.
- At the prescribed time, we meet on the beach of “Las Croabas”, a small fishing village located on the extreme northeastern tip of Puerto Rico. Your Eco Adventure guides call the group of Kayakers together for a briefing session covering basic kayak handling, rules of the road and the importance of keeping to a minimum any disturbance of the pristine environment of the bioluminescent lagoon.
- 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 greet the adventurer, the mountains of the “El Yunque” Rainforest tower in the distance – a 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, historical notes of interest such as 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 4 other places on earth!
