An uncivilized "wild" redwood forest with ferns that are almost as tall as you and you have to watch your step as ravines can be covered over by fallen trees and years of debris. The link below is to an image of one that appears to be such though it does look somewhat tailored and may be a second growth forest.

I must say that the forests of the Pacific Northwest are on my life list of things to see.

But having grown up and spent all of my life in the Northeastern US, I must say that I favor the mixed hardwood forests of the northeast that are filled with oak, beech, ash, hickory, and maple trees. They have an understory of spicebush, witch hazel, dogwood, serviceberry, and more. With an assortment of woodland wildflowers and plants including bellworts, solomon's seal, jack-in-the-pulpit, mayapple, trillium, bloodroot, wild geranium, baneberries, spring beauty, squirrel corn, ramps, blue cohosh, meadow rue, trout lilies, various ferns, and more. It is my image of paradise.
