  We had a wonderful guide that explained the uniqueness of the bay, the strength of the bioluminescent creatures and how they are intertwined. He also took time talk about the sky, planets, and stars.

  Cool but way overpriced. Teens lost interest very fast and so did the adults. It should be warned too that there is absolutely nothing near the pick up point and if you're on the 10pm tour if you dont reserve a taxi in advance youll be dropped off in the middle of nowhere and left

  We spent two airline tickets on Air Vieques, extra luggage fee of 400.00 because we were coming directly from a cruise, and hotel ONLY to see the bay. So you can imagine our great disappointment to learn it was the cancelled at 4:00 pm the day of the tour. They stated that a van couldn’t be secured for transport to the boat. There were a total of 5-6 people also waiting. We could have driven to the boat considering all of us had cars or hired a taxi to the boat. They offered a next day offering, but we were leaving the next morning. I want the provider to be cognizant of the fact that travelers to this island come for this experience, and unless it is something out of their control such as weather, lack of crew, or broken down boat, they should make efforts to honor the tour.

  Great tour, great guide. We wanted to do the Mosquito Bay tour, but couldn’t manage the logistics on our own. Luckily, our hotel was able to book us last minute onto this tour. Robert, the captain and owner, took care of us from the moment we signed on, arranging our ferry tickets and rides to Esperanza. In fact, Robert and his wife Glenda drove us. The tour itself was simply magical. Robert is the only operator with a boat, which means you see more, get away from the hoards on kayaks, and can truly enjoy every minute. The stars were fantastic and Robert pointed out all the constellations. We had dinner at Duffy’s while waiting, and the fish tacos were the best. Can’t recommend this more! It was totally worth the time spent. Thank you to Robert and Glenda!

• Voted as our favorite activity in Puerto Rico!

  We had high hopes for our tour of Mosquito Bay in Vieques with Isla Nena Bio Bay Tours, and our experience was absolutely amazing! We chose a date after checking moonrise and moonset, and by choosing a date that had moonset before sunset, we were guaranteed that the light of the moon would not impact our tour. We also chose to take an electric boat rather than a kayak because of our ages (60s and 70s). We boarded a van at the pickup site on our confirmation email, and had a bumpy ride over unpaved roads to the bay. The walkway onto the boat was narrow, but 2 members of the staff walked in the water on either side of the walkway, offering hands when needed to get us to the boat safely. We cruised out to the center of the bay, enjoying the commentary of our guide describing both the bioluminescence of the water and the abundance of stars overhead. We were given poles to stir the water and were amazed at the resulting glow. Fish that were swimming near the surface or jumping in the bay created an effect similar to shooting stars. Our guide answered many questions, and pointed out constellations in the clear sky. It was a beautiful experience, and I would highly recommend it to anyone visiting Puerto Rico

  We just returned from our boat tour with Eddy as the captain and he was great. So knowledgeable. The Bay was beautiful and the night sky was full of stars that he also pointed out planets and constellations. The bio bay was so cool and the fish were fun to watch. I would so recommend this tour.

  Terrible customer service - would not recommend this tour company. Received a text earlier today stating all tours are moved up by 30 min. Then I receive another text an hour before we were supposed to meet for the tour. Then would not answer the phone when I called in response to the cancellation text. Then they call back 15 min prior to the initial departure time stating “it’s still on and the boat ‘issue’ isn’t that big of an issue“. I call them back only to be told they decided to cancel again (all within a 5 min timeframe).

• Best Bio Tour!
