Was great! We took the 6:30 tour and was definitely better than the 8:00pm tour due to the profound darkness you are kayaking in.

We went on the 6:30pm tour which actually worked out fine because we had some light to maneuver through the mangroves, and then darkness in the bay and on our trip back. I got wetter than I thought I would, so be prepared. Make your reservations in advance or you will get closed out. You will be on the move... More

It costs 40-50$ for Kayaks and 90$ for electric boat. All tour operators have their base at Las Croabas where they brief about the tour and give safety guidelines.My Suggestion will be not to miss the briefing section. You will realize its importance as you kayak through dark mangroves. Each trip takes about 2.5 hours from start to finish and... More

La Parguerra. My visit was during the early 1970's. It was beautiful. Very alive. Today not so much. Fajardo: Again I found this bay during an office beach fishing trip (mid 1970s) and remarked it was a bio bay. I've never visited it again although I now have lived in the Fajardo area for the past 7 years. Vieques..We lived... More

the glowing water was so cool I just loved it but I think we had the most fun trying to navigate our kayake down the narrow straight of Mangroves. we laughed so hard we nearly fell out of our boat. no need to worry the water is only 3 feet deep. Pair it with the rain forest for a amazing... More

Unbelievable experience. Kayaking through mangrove trees past sunset out into the open lagoon waiting for darkness to see the planktons light up. It's amazing. With only 5 bays like this in the world that light up every night its something you shouldn't pass up. I'm not sure what all the negative reviews were about, quite frankly I was shocked to... More

We had a great experience with Pure Adventure kayak trip to bio bay on friday 4/4/2014. Our guide Javier was excellent. The glow from the bioluminescent plankton was amazing that night. We took the 5:40 ( early ) tour and it was perfect for our 6 year old and also was less crowded. This trip takes about 2 hours and... More

If you're going to do this, don't do it the way I did: plan ahead! This tour is EXTREMELY popular and most of the spots fill up quickly. Make reservations ahead of time. I was fortunate in that I showed up with my friend at the last minute, hoping there would be spots due to cancellations, and we were able... More

Pretty much one of the coolest experiences of my life. We took a kayak tour to go to the lagoon which was filled with the bioluminescent organisms. The kayak trip there was dark and quiet and took us through mangroves which where lit up at their roots by the bioluminescent plankton. Upon arriving at the lagoon, it was like holding... More

This is a truly out of the world experience. I would suggest booking it for a Sunday when it is less crowded with IO PR Eco-Tours. The other factors which impact the glow is the moon phase and tides.
