Fajardo: Bio Bay Kayak Tour


About This Experience
The cheapest of the Laguna Grande tours we cover at $72, and the one that includes the most for the money. You meet at Kayak Village in Las Croabas, learn the basics of kayaking and the rules of the nature reserve, then paddle towards the red mangrove channel that forms the entrance to the Fajardo bio bay.
The route is timed so you enter the channel in daylight and come out into Laguna Grande as the sun goes down. Sitting in the lagoon under the constellations, every paddle stroke sets off sparks in the water and the kayaks trail a swirl of light behind them. The return leg through the mangroves happens in full darkness, guided by low-intensity navigation lights fitted to the boats — which is a genuinely different experience from the paddle out.
What you get for the price is unusually complete: navigation lights, skin-friendly repellent, seasonal fruit and protein bars, secure storage for valuables, first-aid and kayak-towing equipment, and photographs of your own tour. At 4.4 from 305 reviews it sits mid-table, and the recurring complaint is worth repeating: several reviewers mention inexperienced paddlers bumping into them in the channel, and that you have to walk a stretch to reach the launch.

What Travelers Say
Rated 4.4/5 by 305 verified GetYourGuide travelers.
It was awesome! Biggest issue is the inexperienced kayakers who were on the trip with us - they banged into us and made it harder. I also think everyone needs to know that you have to walk through waist high water to get into the kayak. So much fun!! Loved it so much and it was invigorating.

The activity was awesome! All the guides were super helpful and kind. There wasn’t much glow but they did such a good job to make sure it was an enjoyable experience!

Frequently Asked Questions
What makes this cheaper than the other Fajardo tours?
Mostly the start point. At $72 it launches from Kayak Village in Las Croabas with no hotel transfer, so you are not paying for the round trip from San Juan. The inclusions are actually more generous than the pricier listings — navigation lights, repellent, fruit and protein bars, valuables storage and tour photographs are all in the price.
Do I get photos of my own trip?
Yes, photographs of your tour are included. That matters more here than on a daytime trip: phone cameras generally cannot capture bioluminescence, and several operators on this island state plainly that no camera guarantees the glow will show up in your shots.
How dark is the return paddle?
Fully dark. The route is timed so you reach the lagoon around sunset and come back through the mangrove channel at night, with low-intensity navigation lights on the kayaks marking the way. Guides lead the line and the channel is narrow, so you follow the boat in front.
Can children do this tour?
From age 6. Children between 6 and 13 must share a kayak with an adult, and 13 to 17 year olds need an adult on the tour with them. There is a 240 lb per-person and 425 lb per-kayak weight limit.
Is there a walk involved?
Yes — several reviewers mention carrying gear a short distance to the launch. Wear water shoes or something you can walk and paddle in rather than flip-flops you have to hold.
