The current tallest tree according to the tree enthusiasts who keep these records, it is the Hyperion redwood tree.

It is 386 feet tall to the lowest edge of the trunk (on a slope) but 379.5 feet above average ground level. It’s 15 feet thick and some have estimated its age at 800 years old.

There are records before 1900 of trees as tall as 390 to 424 feet tall in the Redwoods, but those were exceptional specimens.

National Geographic did a survey in the 1960’s and declared that the tallest tree in the world was in Redwood National Park along Redwood Creek in what came to be known as the Tall Trees Grove.

Since then, there have been many less publicized surveys that have found taller trees. Some of them are in the Rockefeller Forest section of Humboldt Redwoods State Park. Most of these surveys keep the actual location of these trees a secret so the public won’t know where they are.
