The city that is home to the tallest tree is undisclosed, as the exact location of the tallest tree known as Hyperion, a coast redwood, is kept a closely guarded secret. This remarkable tree is found in Redwood National Park in California, USA. It was discovered on 25 August 2006 by Chris Atkins and Michael Taylor, both from the United States. The coast redwood, scientifically known as Sequoia sempervirens, is an iconic species known for its incredible height and longevity. However, due to the importance of protecting Hyperion and its habitat, its exact city location is not disclosed to the public.
