Just like that , just google it as Devils Den in Florida
Who cares it's fun af it's just a name....
They say the devil lives in that hole. If you go at night you can see him his red eyes in the water. Never go down there at night
I believe the name Devil Den came from the fact that the spring is located underground and as Alan said above the steam in the winter month rises above When the cold water hits the colder air ...
The steam coming out of the hole in the ground during the colder months in Florida got it's nickname from the locals at the time.
