Absolutely awesome experience that we'd love to repeat. Captain and crew were so knowledgeable and passionate about these gorgeous creatures and added bonus of swing over the springs. Big wow. relaxed but really professional. Wonderful.
First of all you float with the manatees, not swim. Next I think Viator should now that its seasonal, whether you see them, in our case were told that we could see them from boat, only a blur as the one only manatee that they new where it was was, a fair distance from the boat, and it was a very young one. The tour tried to fill in the time for the tour by taking us to see Turpin fish and a dolphin that had come into the river. This was the first tour I booked, and worked every thing else around the manatees, so we were very disappointed that that was all to see. It was also very hard to find where the tour was, when we drove ourselfs.
Our tour guides were very nice and professional...the manatees weren't plentiful, but we got lucky and were able to swim with 2 manatees which was very cool!
