Hyperion is the world tallest tree. It is currently located in Redwood National Park, California. Even though we know it is in Redwood park, the exact spot is not known due to concern over vandalism. Hyperion's height is 379.1 foot-tall.
Just to add couple more facts:
- Redwood National Park is bought during president Carter administration in 1978.
- Two hikers named Chris Atkins, and Micheal Taylor discovered Hyperion.
