Quinault Giant Sitka Spruce

Known to some as the Valley of the Giants, Washington's Quinault Valley is home to some of the tallest trees in the world. The trees in the Quinault Rainforest are well watered with an average rainfall of 12 feet a year.

Though the redwoods of Northern California have a slight edge when it comes to height, the temperate rainforest is filled with towering evergreens, including six champion trees, recognized by the American Forests Association as the largest of their species. One of those champions is the Quinault Giant Sitka Spruce, which stands 191 feet tall and measures more than 55 feet in circumference. Estimates have put the age of this tree at roughly 1,000 years old.
