A great nature experience
, Mar 2020
The experience was wonderful, however there is no mention in the description that the tour starts approximately 3 hours before the posted time. We were a group flying into San Juan from different parts of the US and Canada scrambling to make this from our flights. Good thing I had called the day before or we would have had no idea. Aside from that I greatly enjoyed this tour and the bus driver and kayak guides were wonderful. Don't go just for the light up Bay as it's not overwhelming but the mangroves trees at sunset were beautiful.

I called that nothing more than a glorified kayak trip! We were not put in the glassbottom boats due to my weight and then put me in a kayak that I had problems getting out of because I have had past knee surgeries!! Then we float around for 40 minutes waiting for the sun to sit when our original reservation was at six which would put us out there at eight but then we ended up having to be there at 3 PM with people flying in that day! Then cover a our heads with a tarp because it was a full moon at night so that we could see nothing in the freaking water don’t waste your money!

Hade a good time and friendly staff. The bioluminescence was not as advertised in the pictures. We went under a tarp to see them in the water. I recommend taking the later tour when it is darker out.

Crew at the bay were extremely helpful and hard working. Felix, our driver to and from made the drive very enjoyable. Couldnt ask for a better time.
Disappointingly little bioluminescence when we were there
, Mar 2020
This tour was rather disappointing. We have no issues with the outfitter—they provided everything they had promised in a very efficient and professional manner. The canoes were modern and comfortable, and the guides were courteous and friendly. However, the dinoflagelates chose to be very shy while we were there. We saw only a few faint, widely scattered sparkles in the water. We had scheduled our tour to coincide with the new moon, which is when the “show” is supposed to be the best. However, for some reason there was very little “show” that night. Perhaps the rain earlier that afternoon had temporarily adversely affected the water temperature or water chemistry. I hope that our disappointing experience was a fluke rather than a trend. If our experience is representative of the best this bay has to offer these days, then there really isn’t much reason to take this tour.

Dear Tom, We are sorry the tour fell short on expectations the day you participated. We appreciate your acknowledgment on our service quality and professional staff. As we have clearly advised on the tour description: "The bio bay is an unpredictable natural phenomenon that may be influenced by multiple factors. Bioluminoscity level can vary from very visible to minimum or none without any previous notice." This is why the tour is not only focused on the bioluminescence, but on the aspects of the reserve and entire eco-system participants experience during this adventure. Kind regards,

Great driver Jose and tour was simply “ok” but time for bioluminiscense was tooo short to have a real experience :(
Nicely organized tour

The pick up was on time, the bus was comfortable, the luminescence was not great due to a pretty bright moon, but that is not the organizer's fault.
Buyer Beware
, Feb 2020
Was not happy at all. The actual guides were great, but the rest wasn’t good at all. The biggest issue is that when you book you have to give the weights of all passengers. The weights meant that we needed TWO of the bigger boats. The group tried to only bring one. We were told that because one person was heavier that originally reported, but still under the parameters of needing the second bigger boat, our party was going to be split up. We didn’t want that as we wanted the experience as a group. We were so disappointed and half of our group didn’t go. I asked for a partial refund but was refused because of the original weight being wrong. Yes, it was wrong, but still didn’t change the fact that we needed the second boat. Caveat Empour
It was nice!

It was a different kind of trip!! Instructors were extremely friendly and helpful!! A bit scary not going to lie, but totally worth it!!
Very good and beautiful

It is a very good trip. The driver pick up us on time, and when we arrived, everything was settled very well. The guides are welcoming. Although we didn’t have boating experience before, it is okay.
