Bio-Bay Kayak Adventure Tour in Puerto Rico

Bio-Bay Kayak Adventure Tour in Puerto Rico

Don't let your day end when the sun goes down!

Enjoy a relaxing kayak tour that leads to the fascinating Laguna Grande in the town of Fajardo. Under a blanket of the night sky and the historical lighthouse of Fajardo, you can touch the waters that glow with Bio-luminescent Organisms and take in views of the only U.S. Tropical Rainforest, standing majestically in the background.

Tour includes kayaks, life jackets, refreshments, and two to three guides, depending on group size.

Please Note: Bio-luminescent Organism visibility is currently very low due to several environmental factors, and this tour is temporarily unavailable. The lagoon is expected to be in a recovery process until Spring or Summer of 2016. Until then, please consider the following night kayak tour:

Tour Itinerary

You will be outfitted with all the needed gear which includes: double kayaks, backrest, paddles with leashes, PFD's (Life jackets) and two to three Guide Kayaks with all needed safety equipment, lights and refreshments. Your guides then make sure you have the necessary Botanical insect repellent as well as a brief course in kayak 101 safety training which covers all aspects of the tour and operation of your kayak.

You will then head across a small fisherman's cove to the entrance of Las Cabezas de San Juan Reserve. Here, you enter a mystical channel that leads to a peaceful place where the mangroves create natural tunnels and the sights and sounds of nature surround them. Along this 30-minute paddle, your lead Guide will be stopping to give commentary on the following points of interest:

  • Mangrove forest and the different species
  • Bird life that inhabits the area
  • Aquatic marine life that use the lagoon as an estuary
  • Information on reptiles such as Tree Iguanas
  • Rainforest and its role for the lagoon
  • Lighthouse History

At this point, the group will enter the lagoon called Laguna Grande (large lagoon). Here, the paddle is along the edge of the mangrove forest as you watch and listen for movement in the mangrove trees. Look for the beautiful Great White egret, brown pelican, 35 species of warblers, great blue heron & yellow crowned night heron - all the while hoping to catch a glimpse of a shooting star.

This will lead the tour to a break point were beautiful views of the Rainforest and the lighthouse of Fajardo accompany interpretation of the natural area along with good conversations. At this point, you will be about one hour into the tour and, under a blanket of stars, the group will start its return to the departure site. This takes about 30 minutes. Snacks and refreshments are provided at the end of the tour.

Minimum age is 6. Minimum 6 persons required to operate. Maximum weight per kayak is 500 lbs. Tour provides for optional hotel pick-up and drop-off at San Juan hotels. Please order online or call to order or for more information.
