Amazing Trip and unforgettable. I would recommend going early in the morning, as that is when the manatees are out and about. We got in the water, which was freezing and were soon surrounded my many manatees. The tour guides tell you all of the rules before you go however and sadly you are not allowed to go up and touch them, as it is illegal, but you are allowed to touch them if they swim up to you. There were two manatees that came up to us and kept nibbling on our swimsuits and it was amazing. I would highly recommend going to swim with the manatees and it is something you should not miss.
