They're world famous. The redwoods at the Redwood National and State Parks in Oregon and on the north coast of California are the tallest trees on the planet.

Stratosphere Giant held the title for tallest tree on Earth, but three others the Hyperion (378.1 ft.), Helios (376.3 ft.) and Icarus (371.2 ft.) superseded it when they were discovered in Eureka, Calif.
