This is one of the most famous parks not just in the United States, but the entire world. It boasts being home to the tallest trees on Earth (which span 350+ feet in height). The Parks also protect vast prairies, oak woodlands, wild rivers, 200 miles worth of hiking trails, and 40 miles of rugged coastline. The spectacular redwood tree tends to live a long time due to its resistance to things like fire and insects.
