Full description
Join your expert tour guide for an all-day excursion to the El Yunque Rainforest, then kayak with glowing planktons at a bio-luminescent bay. Start your adventure with a visit to the lesser-known zone of El Yunque, the only tropical rainforest in the United States. Hike and explore this off-the-beaten-track habitat. Take a dip in a waterfall or natural pool, or try out the waterslides. Hear fascinating stories from your guide about natural and local history. Spot native flora and fauna, many of which are not found anywhere else on the planet. After the hike, take a break with some lunch at a local restaurant. Then its time for a kayak adventure through mangrove channels leading to the Laguna Grande. Meet the glowing microscopic planktons capable of producing natural light at the touch of your hand. Paddle in this remarkable yet safe environment. Explore these amazing creatures up close. Watch how every stroke of your paddle leaves behind a glowing swirl of blue light that resembles fireflies. Learn how this fragile and unique ecosystem maintains a perfect balance of life.

The hiking trip to the waterfall/river was so much fun and the tour guides were awesome. Very involved and made sure everyone was enjoying themselves. Breathtaking views and the water felt amazing cause it was so hot!! Bio Bay Kayaking was an absolute waste of time and money. For starters, the water smelled like we were kayaking in a cess pool. The water was black and smelled like rotten eggs. Didn't seem very sanitary or safe for anyone to be in. Then we were lined up in our kayaks and covered with a tarp full of sand in order to see the plankton light up (which they didn't) they clearly stated this wasn't guaranteed but according to other reviews it seems like it doesn't happen any time of the year. So we literally just got covered in sand from head to toe for no reason. I really do not recommend this activity to anyone.

I think people should knows this hike is NOT easy. We were exhausted after the hike and ended up skipping the kayak experience because of this. With that being said the hike was amazing. Our tour guide Felix was great and everyone made it back in tact. I highly recommend.

For the first portion of the excursion (El Yunque Rainforest), Felix and JC were absolutely incredible and are the only reason why I would rate this 5 stars. They were very knowledgeable, friendly, encouraging, and fostered a familial environment. I would recommend them 10 times out of 10! They also provided unlimited bottles of water and snacks. I would not, however, recommend the Bio Bay Kayaking. I can't even remember our tour guides' names because they did not engage at all. Outside of providing instructions on how to kayak and what path we should follow, they did not talk to us. They mostly only spoke with each other on the walkie talkies and did not teach or show us much about the wildlife we had paid to see. The bioluminescence in Laguna Grande is not impressive - I would recommend 0 out of 10 times. If this is truly an experience you want to partake in, go to the islands of Vieques or Culebra.
