Everyone needs to see this bioluminescent bay once in their life. Some say the one in Viequez is better, but it's not. This one is the best. You kayak through a little canal and before you know it, the water starts glowing. I have never...More

If you go to the Bio Bay, take a Kayak or don't go at all. We were in an electric boat and saw very little of the lights. It wasn't the fault of the excursion, you just don't see anything from a boat. We were...More

I have read many reviews about the bay and can only relate our own experience, it was awesome! Went with Eco Tours and had a nice time. The staff was knowledgeable and the labor to get to the bay was worth the experience..very cool!!

There is nothing like it anywhere else in the world. You will be mesmerized by the luminescence. Take plenty of pictures. Do not go on a full stomach if you dont have sea legs.

I liked the kayaking in the mangrove swamp, but at the full moon the bioluminescence was underwhelming. A few sparkles in the water. I pictured it differently, but it was still cool. Seemed poorly organized, relying on you to stick with your guide in the...More

Recommend to visit ONLY if the new moon. This is when you are going to have the best experience. If in full moon, do not loose your time

Trip is worth the money make sure you choose dark night. Don't rely on their calendar as it doesn't give right information. Use your judgement to choose the day/night.

This was my first time kayaking and having to kayak a mile to the location and a mile back in complete darkness was terrifying. However, the staff were really great and I was able to the survive the trip. As for the glow, the moon...More

We will be flying into San Juan and staying overnight to depart on a cruise. We would like to take the Bio Bay tour since we will be there overnight. What hotel or area would be best for us to stay so that we are convienant to get to the Bio Bay tour and get up the next day to head to the port in San Juan?

If it were me, I'd rent a car, drive to Fajardo to do the bio bay, then drive back, return the car, and stay the night in San Juan... Embassy Suites or wherever. If you drive back in the morning you have to deal with rush... More

There were more than two groups that ran the tours. We went through Ecotours. It's the same service regardless of who you use. Go with the lowest price you can find.
