Highly recommended experience - The excursion is very pleasant. We did the tour and swimming overlooking the sunset, and although the sky was cloudy it was enjoyed equally; and then we continued the tour to swim in the bioluminescent bay, which was a real sight.

Outstanding and best value! - This tour was incredible and far exceeded our expectations. There was plenty of time at both locations to enjoy the water and the bioluminescence was amazing! I also loved that the tour was smaller, they don’t pack in a million people. It felt very private and peaceful. So unique and by far the best value for a bio bay tour!

Late Night Tour in the Bio Bay - Nothing short of amazing and magical! We had plenty of time to swim in the water and truly appreciate this natural phenomenon. Ryan was kind enough to take pictures for us and tell us a bit more about the Bio Bay itself. Highly recommend!

Amazing experience! - Hector and Ryan were great! The late evening into night boat ride to the sand bar and then the bioluminescent bay was incredible. Magical. My kids and I were in awe. I highly recommend going here.

Wonderful - Our guides were great! We didn’t actually get to see the sunset due to weather but the swim before the bay was nice! The bay swim can only be described as magic.

Repeat customer!!! - This is the second time I’ve booked Mareaito bio bay tour! The guides are always so kind, gracious, informative, and best of all, funny! Captain Ryan was awesome!!! I always book the 6:30 tour. You go to cayo caracoles to watch the sunset then off to the bio bay! Total magic! Best tour ever! I’ll be back again!

- Everything was great! The crew and the experience were worth the drive from San Juan. Ryan and Ariana were knowledgeable and able to answer all our questions. This is the one bio bay you can swim in so it is worth the experience. The only thing I would do different is show up earlier and explor the town or book an Air B&B overnight.

Best La Parguera Biobay Tour - This biobay tour is the best way to experience the bioluminescent bay in La Parguera, Puerto Rico. Being able to swim in the bay, instead of just kayak in it or take a glass bottom boat, sets this tour apart.
The guides were knowledgeable, friendly, and professional. The boat was clean and well-maintained.
Highly recommend!
