4.00Good experience, tour guide was mostly friendly, had plenty of information. Explained area and bio bay well. Could have done without hearing about the stars and spent that time kayaking since that is why we were there.

5.00Fun experience. Pick up was a bit confusing. There wasn’t a clear sign and since the pick up location was a dark Parking lot we weren’t sure we were in the correct location.

5.00We had a great time at our bio bay tour with Emma! She was very knowledgeable and a great communicator. The stars and the bay were breathtaking. Highly recommend if you’re looking for a wonderful experience that is not too strenuous.
Amazing!

5.00Absolutely gorgeous. The bay is incredible! We went on a moonless night so the bay and stars were sparkling. The guides were excellent at keeping us safe and educated on the bay. This company keeps their groups small which was a bonus as some groups had 20+ people with other tour companies. We made the trip to Vieques specifically for this experience and it was worth it!
