My wife and two daughters and I had a great time - we went on the later 800 pm tour, and I'd recommend the earlier 530 tour for inexperienced kayakers or small kids, who can get scared I. The dark. The adventure of kayaking through the mile long mangrove tunnel was as much fun as the bio bay itself, which was pretty cool, but not super spectacular, at least on the night we went. All said though, we had a great time and Island Kayaking Adventures did a very good job and had nice friendly guides. read less

Las Cabezas de San Juan is a beautiful place and they (Island Kayaking) helped us experienced it further. The guides instructed us and our little girl on the safety and procedures of the tour as well as how to better use de kayak and oars – pretty important for the 7-year-old with us. Once the tour started there were four guides with the group (about 16 persons in the group) and they were always close by making sure nobody got stuck in the mangroves ?? ??♂️. Once we arrived at the Laguna Grande we could roam the area close by. Then they gathered everybody as the night finally came around to explain how bioluminescence works and to experience it first hand. It was amazing and beautiful!.
We stayed there for about 30 minutes and started to head, which was an adventure in itself. Traveling the channels of mangroves at night it is funny and cool. There are light in the kayaks and the guides have lights on them too but it's pretty dark nevertheless so it was an engaging experience to hear the animals at night, see the starry sky and just be surrounded by nature – and some "light" crashing onto other kayakers.
Soon after that, came the end of the adventure, everybody happy, our girl was very excited about what she learned and experienced. I fully recommend this trip to anyone living in Puerto Rico or visiting. It's a must! read lessgabo_deleon7/02/2019 -
Great Bring lots of mosquito repellent and wear old shoes. And be prepared, you will get wet from the waist down. Still, an adventure not to be missed.

We had a very large group of 10 - 12 kayaks and it was a little stressful to line up all the kayaks twice. The kayak behind us kept hitting us, and the other group was very loud with talking. It was a little crowded with all the other groups as well. If you are not a group of 2, you will be separated from your other party and may not see them for the trip. That being said, the kayak ride out there through the mangroves was so cool. You could here all the sounds of the forest, and the trees make a canopy over you. Once we were out there the 4 grouped kayaks put a tarp over our heads (? Covid safe) so we could see the effects. Although the lead seemed nice and friendly, definitely an excursion feel to the whole trip. I don’t think you can see it any other way, so worth it to see the phytoplankton natural wonder. All the other groups seemed to follow the same path, so issues not unique to this company. Overall, it was a B experience, and I would do it again. read less

The guides (Pedro, Kenneth, Belin, Celix, and Talia) were amazing. They were funny, knowledgeable, and very helpful. Some reviews have complained about darkness or running into trees, but it’s not nearly as precarious of a situation as they make it sound. There are lights on the boats, and once you get the hang of kayaking, you shouldn’t have any issues. read less

I was a bit wary since we booked last minute and all of the other companies were booked up, but Island Kayaking Adventure was fantastic. After a quick safety briefing we climbed into out two man kayaks and headed out into the water. MAKE SURE THAT YOU ARE GOING ON A DARK NIGHT WITH LITTLE MOONLIGHT! It was nearly pitch black, so we followed the glowstick on the kayak in front of us. The path through the mangrove trees was good for a laugh as everyone was bumping into trees and the kayaks around them. About half an hour in, the water began to glow as we paddled. By the time we emerged into the bay, the water around us was bright. You can't get out of the kayak as your body oils are bad for the ecosystem, but you're free to paddle and splash your hands. I'm not a big kayaker, but even when my arms were tired I didn't want to stop paddling because it was so beautiful! read less

As we were running late, there called me and provided detailed directions on how to get there. On land and in the water we were led by Kenny and the rest of the professional crew. They asked that we be respectful of this unique place they call their office. A quiet paddling experience through the mangroves culminating in an education in the “lights” below and way above the water. We also had fun along the way making for a great experience. 28 March 2022, 6:45PM. “Minnesota” read less

The stars were spectacular and the instructors were very friendly, humorous, and truly made the experience. Two people to a kayak and we all went single file down a mile long channel to the Laguna.

The tour guides were helpful and patient. If you are going to take this tour it would be helpful if at least one person in the boat has some kayaking experience to sit in the back. It will be very dark, the canal is small, fish occasionally jump into the boat, it may rain, you will run into trees and there are many kayaks (15-20) in the group, some with people who are clueless and panicking, or think they are in the Olympics. I enjoyed the kayak adventure and the tour guides. The only thing that kept this from being rated higher was the others in our group. A smaller group divided among tour guides would have been more my style. read less
