We are sorry to hear snot your experience but it really does not seem possible hope you described it. First off, you did not have to walk 5 blocks, there is a parking lot there that costs $5, but you CHOSE to walk the 5 blocks. Secondly, we don’t just hand you a kayak and say “here you go,” we give you a map and tell you where some springs are. The springs are literally marked on the maps….. that’s where the clearest water is. I’m guessing you are just one of the people who do not listen to instructions as you can read from our other reviews that people LOVE how clear the water is, and how great our launch guys are…. Also, it’s a 640 acre refuge, as manatees could be anywhere. During manatee season there arecertain spots you will always find them, but in the warmer months they could be anywhere. They are not in cages like a zoo, you paddle around and look to find them. It’s sad that you came to such a beautiful area and were so miserable.
