If we could give higher than 5 stars we would. From start to finish the tour was friendly yet professionally managed. Despite taking the tour in the summer we were lucky enough to experience excellent conditions. Crystal clear water and almost immediate interaction with Manatees. Wade was an excellent captain and kept up a near constant narration of local stories and interesting manatee info. We took the early morning tour and were lucky enough to find the manatees within 10 min. Trish was our swim guide and as we approached our first manatee you could actually see the calf interacted with her in a very familiar manner which led to our entire group having an amazing experience. Additionally, Trish had one of the highest quality underwater cameras I have seen and made sure to get unforgettable pics of the entire group! Excellent, knowledge, concern for the manatees and environment and group safety, I cannot recommend River Ventures enough ..A++
