Crystal River & Three Sisters Springs — Crystal River

This is the only place in the United States where you can legally swim with wild manatees, and if that sentence alone doesn't make you want to go, we can't help you. During winter months, hundreds of manatees migrate into the warm springs at Crystal River, and you can get in the water with them on a guided snorkel tour. Jamie got so emotional the first time a manatee swam up to him that Julie had to remind him to breathe through his snorkel. Even if you don't get in the water, the Three Sisters Springs boardwalk lets you watch them from above. This is a bucket-list Florida experience that most tourists never even hear about. Best time: November through March for manatee season Cost: ~$30-65 for guided swim tours
