Keep tabs on the spring green up at Mammoth Cave National Park via the park’s webcam, overlooking Green River.
Spring, summer, fall or winter — the park always looks inviting. And as the guides like to say, “it’s always a good day to go in Mammoth Cave.” Why? because the cave air is always 54 degrees F; cool in the summer, balmy in the winter.
