The California Redwoods are the world’s tallest species of tree. I have no idea how these trees got so big, but they sure are awe-inspiring. The Redwoods are so big that in order to properly show their size, you really need an everyday object or a person, for scale. Like a banana. Aside from the trees themselves, Jedediah Smith Redwood State Park near Crescent City, CA, has tons more nature to offer.
