My wife and I were referred to AVI by friends. We booked a wave runner tour and there were two other gentleman in addition to us. AVI took us all around the 10,000 islands weaving in and out of the mangroves eventually being at Pumpkin Bay. On the way there and back, we saw numerous dolphins and were able to be near them on our wave runners. The dolphins followed right beside or next to AVI's wave runner as well as ours. We saw more dolphins than we have ever seen on a day trip and were closer to them than ever before. AVI is truly the "dolphin whisperer" and very knowledgeable about them, the mangroves and the eco system there. He is also a great photographer and at the end of our trip, provided a flash drive with pictures of the day. We highly recommend booking with AVI which we will certainly do again. If we could give him a rating higher tthan five, we would not hesitate in doing so.
