No doubt you've heard of cage diving with sharks...so..let's try it with crocodiles!
In a wildlife ranch in South Africa, diving with crocodiles is the newest thrill for guests to take part in.
Crocodiles sometimes see humans as prey which makes cage diving all the more interesting.
The manager of the park says people get the wrong idea about crocs, that they're sluggish reptiles basking in the sun all the time.
He says it's thrilling to see them close up.
He would say that, of course.
"Oh, it was amazing. This huge and giant animal is so close to me under the water. Yeah, I was scared, but it was great," said Tabea Heck.
"They're eating so it feels like they are gonna jump at you and it's just super exciting," said Anneliene Farlin.
The park officials say they are getting visitors from around the world to swim with the crocs.
