Horse Cave Fire Chief Donnie Parker said the tour groups had been inside for several hours prior to being rescued.
Parker said two local police officers who tried to rescue the tourists were among those trapped. He said four people were able to escape earlier but didn't have details about how they got out.
The chief said the rising water was caused by heavy rains in the area Thursday afternoon.
