Once in a lifetime experience!

Ok, let me start by saying that my husband and I tried very hard to book a tour to see this bay! We called at least 15 different tours and they were all booked! So, with that... read more

Ok, let me start by saying that my husband and I tried very hard to book a tour to see this bay! We called at least 15 different tours and they were all booked! So, with that being said, book as soon as you know you're visiting Puerto Rico! We searched online and read that this can be done without... More

The trip was worth every penny. Don't kayak! We rented an electric boat for $50/person. It was safe and the guide was very good at answering questions and point out important ecological/biological facts. There are 2 companies on the island that offer electric boat tours.

I took the tour in the Laguna Grande bay in March 2015. I will give my best description of what to expect: We arrived for an 8pm tour - which by the time we were loaded up and off was about 9pm. It was very dark out - only light was the glow from nearby towns and some street lights... More

you see some glow in the water but no where near what the brochures and advertisements claim. We did the walking tour along the bank / boardwalk through the nature center because we heard the mosquitos were unbearable if you take the kayak trip because you are stuck waiting in so many areas and can't keep moving like you can...

Supposedly there are only 7 such bioluminescent bays in the world, so it's certainly an uncommon adventure. There are usually two tours available, one at 6:00 and one at 8:00. I would recommend the 6:00 tour as there is still light available when you go through the mangrove channel the first time. Coming back, it's close to pitch black so... More

Gerat fun and exciting crossing the marina and kayaking through the canal in the pitch dark. Just check lunar calendar and make sure NOT to book on a full moon.

Just a tip, Bio Bay is also called Mosquito Bay, not because of bugs, but because of a pirate who hid back in the bay and his boat was called the mosquito. however, we still all protection against getting bites. I recommend vitamin B 6

The trip was fun while there was a little light, but the trip back in the total darkness was actually dangerous. Someone could have had an eye poked out with tree branches that dig in the creek. Inexperienced kayakers almost ruined our trip.

We rode a motorized boat through mangroves and out into the bay. Stars were above us and below us. Every time we put our hands or stick into the water, water illuminated with magical glow. It was wonderful. I had considered doing the kayaking and our boat passed by scores of them. Let me just say I'm so glad we... More
