Probably nice for small kids who get excited by walking around a forest in the dark and seeing lizards. The crew is nice but for a person with some biology / ecology background - the 2.5 hrs (excluding the time to get there and back) were not well spent. If you DO decide to go, choose a moonless night otherwise... More

Kayaking in the dusk to dark with a group is fun in itself. Then you get to see a true national treasure with the bioluminescent waters. It was like being in a movie. And you do not need to be physically fit to do this.

We have never been to a "bio-luminescent" area before and I was unsure what to expect, but it was quite fascinating. Our trip landed on a date when there was some moon light, but the glow in the water was still very evident and unique. We kayaked with the ECO adventure group and I think you would get the same...

We had been looking at many of the San Juan Tours that included the Bio Bay. All of them included the kayaks and my wife and I didn't feel the need to kayak through the mangroves in the dark. We looked at taking a taxi from San Juan, but it seemed pricey, so we pretty much had given up on... More

My Hubby and I signed up for the latest, darkest bio bay kayak tour we could. We were both excited to see the bay after reading so many great reviews online. We picked the darkest possible night based on the moon calendar. Our group leaders were fun and knowledgeable about the bay. There were several groups all kayaking into the... More

We visited a few years ago and did the evening kayak tour. Make sure to wear a swimsuit and bring a change of clothes as you will get wet. I recommend bring a cushion or towel to put behind your back as the kayak seat was a little awkward. The lights in the bay are awesome and a wonder of... More

We went on on the electric boat tour of the Bioluminescent Bay in Fajardo, and it was a highlight of this trip to PR. Not only was it interesting to hear about the mangrove trees and how their filtration system works, it was also beautiful, even in the dark. The bay is amazing- we saw several fish, jellyfish, and shrimp... More

We booked a tour of the Bioluminescent island excursion on a recent trip to San Juan PR. We arrived early and were greeted by Mario and Jeff who gave us a tour of the bay and the nuances before we boarded. Mario is an amazing guide and Jeff saved us from numerous contacts with flora and fauna. The information Mario... More

I always feel one has to visit those places in a country that are unique in the world. That is why I really wanted to go here. It is a beautiful site to see the bio-luminescence of the lagoon; but is way overcrowded. Many companies try to make a lot of money by squeezing as many tourist in there in... More
