Very well organised, had an amazing experience snorkelling with these wonderful Manatees. We particularly liked how conscious River Ventures are of obeying the rules and being respectful of the animals and their territory. Wade and Trish were friendly and knowledgeable hosts aboard the boat and were very patient and helpful, especially around using the snorkelling equipment. The only negative I would say is that it describes itself as a three hour tour but we actually spent about an hour in the water, the rest of the time was watching a safety video, changing clothes, making our way out to the spring and then doing the reverse at the end. But other than that we would definitely recommend the experience, particularly with River Venture as they genuinely love the Manatees, follow the rules and make sure the animals come first, but you still enjoy yourselves.
