BioBay Kayak Tour
, Jun 2019
This turned out to be an excellent excursion, as everything went our way. We were picked up on time and only needed to stop for one other couple on the way out to the Bay. Then we left in the kayaks before it got dark so the trip out was an easy one, plus got a bit of time in beautiful Laguna Grande before the sun went down. Once it was dark enough, everyone got together and under a tarp to view the bioluminescence. They said it was best case scenario because it had rained recently, bringing all the nutrients from the forest to the water and increasing the amount of algae. Very cool to see. Plus there were absolutely no bugs! The trip back was in the dark but the kayaks were lit and it was easy enough. A bit crowded as people were hesitant at times, but you'd rather that than getting lost from your group. Overall a once in a lifetime experience.

People with no kayaking experience and a dark night are not a safe plan The guides had black or dark clothing on not able to see all who are participating. Rookies were paddling into others boats and causing crashes into the dark mangroves. I got hit in the face by branches at one point due to irresponsible kayak behind me. Safety is not a priority. B as throo.s at site have no toilet paper or paper towels. Longer ride than I anticipated.

Being A non-swimmer and very apprehensive about this tour, I took it anyway. I am so glad I did! It was a great experience and I would encourage anyone who is apprehensive to step right up and do it !
Wonderful experience

I had heard from friends that this is one of the top attractions in Puerto Rico and I wasn't disappointed. Pick-up at the hotel worked great, although I had to call them myself to find out the exact time of pick-up. Originally I had been told that I would get a notification with exact details, but this never happened. But that is the only bad thing I can say about this trip. Transport to the bay worked fine, where we were teamed up in pairs for the kayaking. You have to find the right rhythm with your partner, but then it was a great experience to paddle through the dark mangrove forest and slowly seeing the glimmer appear when the paddle gets in the water. When we reached the bay, it was glowing everywhere. When you put your hand in the hand and took it out again, it looked like stars sparkling in your palm. Amazing experience!

This was our first time kayaking and we had fun, it can be quiet a workout but it’s totally worth it. Instructors were a lotta fun and the whole experience is just beautiful!
Over-rated. Just average

This excursion was over-rated. I’m glad I went but I wouldn’t go again. For what it was marketed as vs what it was was a bit disappointing.

This excursion is terrible. There is not enough time to take photos while you paddle. Also, you have to go to many other places to pick people up so you spend a lot of time in the bus. When you do arrive at the bioluminescence part, they throw a tarp over all the kayaks and people even though it's pitch black already and you drag your arm in the water. There was moon to interfere with the luminescence on the date we went so we should have seen it all well without the suffocating tarp. DO NOT WASTE YOUR TIME OR MONEY..

It was fun a fun trip and definitely worth doing. I preferred the early tour time so that we could kayak into the bay during daylight. Having seen the mangroves in one direction during daylight definitely made it easier to paddle our way back out of the bay in the pitch dark. It's easier if you have some kayak/canoe skills, but even an experienced kayaker will have a difficult time because other people on the tour who can't control their kayaks will be tipping over, blocking the channel, going off course, tipping you over, etc. Our hotel pickup was great. The van was comfortable and we had good conversations with the other people on our tour. The amount of time the drive takes depends on whether you are the first or last person being picked up. Because I am too heavy for the glass-bottom kayak, we had the regular kayaks. In fact, the entire group in our van had regular kayaks so I think that they separate out the two sets of people into two different tour groups. This was actually nicer this way because there wasn't any confusion about who gets into which kayak and nobody in the tour felt like they were getting a different experience. At the kayak launch, the kayak introduction was very brief. In the bay our kayak guide was very informative. He showed us different constellations with a laser pointer while we waited for it to get dark and for our eyes to adjust. The bioluminescent plankton is... different than I expected. The long-shutter photographs that you see make it look like big blue swirls. But in person it's really more like a lot of sparkles around your hands or paddles. Kind of like magic wand sparkles or pixie dust in cartoons. The bay is still recovering from the hurricane, and it's still very neat, it's just not like what you expect when you are preparing for the trip. We put on bug spray and didn't get bitten except for one single mosquito bite on my ear. Although we did wear a long sleeve shirt, so that probably helped. but we had bare legs and those didn't get bitten. Bring a towel because you will get wet from the waist down even if you don't tip over. The driver had towels for people to sit on, but it was nice to have our own towel in addition. The bathroom at the bay is only two stalls so don't plan on being able to change in the bathroom because there is a very long line. Everyone was better off not switching back into day clothes and just sitting on towels to dry off during the drive back to San Juan. The snack that is provided is at the very end of the tour, and is just chips, so have a more substantial snack on your own before you leave on the tour and plan to have a late-evening dinner back in Jan Juan after the tour. You won't have enough time to eat from anyplace at the bay.

Agency has superb customer service, they asked me questions and established that I have booked a tour to wrong place since we wanted to swim in water, not only kayak. Alex was amazing, picked us up from Old San Juan, drove to the other end of the island, waited for us to finish dinner and then we had the most amazing experience inside bioluminescent bay.It is a must for all visiting Caribbean, this world wonder is hard to find. Absolutely fantastic!!! Highly recommend!
