In Northern California, lies the tallest trees on earth, the Coastal Redwood. Standing at the base of Earth’s tallest tree, the coast redwood, is one of life’s most humbling and amazing experiences. These California trees can reach higher than a 30-floor skyscraper (more than 350 feet), so high that the tops are out of sight. Their trunks can grow more than 27 feet wide, about eight paces by an average adult person! Even more incredible: These trees can live for more than 2,500 years. Some coast redwoods living today were alive during the time of the ancient Greeks and Egyptian empires.
