Even seeing the vast natural wonder, it's hard to imagine that there are more species of trees in one acre of the Smoky Mountains than all of Northern Europe.
The park is one of the largest protected areas east of the Rocky Mountains at 500,000 acres full of trees, plants and animals.
It's so vast and diverse that a hike from a mountain's base to the peak can be compared to a 2,000 mile hike on the Appalachian Trail from Georgia to Maine in terms of the different plants and animals you'd see.
The National Park has 100 species of native trees and contains one of the largest areas of virgin deciduous forest in the entire North America. About 95 percent of the park is forested, with 25 percent of that completely undisturbed.
Some of the ancient wonders have records for being some of the largest trees around at over 20 feet in circumference. That is giant!
