I've googled my question but can't seem to find an answer. I was hoping to go snorkeling or diving near manatees in the Crystal River area. I know that this is typically done from a boat, but I don't have a boat and I also read that the 3 sisters spring is accessible without a boat. However, I can't figure out 1) whether or not 3 sisters is closed at this time of year, and 2) where exactly I would park. You search for manatee information and all you get is information about private tours. Are there any alternatives to Crystal River within 1.5 hours of Gainesville where you can dive/snorkel near manatees without a boat? Thank you.
