Common names include coast redwood, coastal redwood and California redwood. It is an evergreen , long-lived, monoecious tree living 1,200–2,200 years or more. [ 4 ] This species includes the tallest living trees on Earth, reaching up to 115.9 m (380.1 ft) in height (without the roots ) and up to 8.9 m (29 ft) in diameter at breast height .
The Roaring Camp & Big Trees Narrow Gauge Railroad is a 3 ft (914 mm) narrow-gauge tourist railroad in California that starts from the Roaring Camp depot in Felton, California and runs up steep grades through redwood forests to the top of nearby Bear Mountain, a distance of 3.25 miles (5.23 kilometers).
Sequoioideae, commonly referred to as redwoods, is a subfamily of coniferous trees within the family Cupressaceae, that range in the northern hemisphere. It includes the largest and tallest trees in the world. The trees in the subfamily are amongst the most notable trees in the world and are common ornamental trees.
[4] [5] The redwoods contained in today's regional park are third-growth trees, many of which are over 100 years old. Only one old-growth redwood remains in the area, a 93 feet (28 m) tall tree that seems to grow miraculously out of a rock on a cliff face near Merritt College, which may have survived because it was out of reach for loggers.

I went to Redwood National and State Parks for the first time. From poisonous plants to the actual height of the trees, here's what I didn't expect.
The National Science Foundation (NSF) initially funded the creation of the TeachEngineering library through its National Science Digital Library (NSDL) program. [6] [9] University engineering faculty, graduate students and K-12 teachers from the University of Colorado Boulder, Colorado School of Mines, Duke University and Tufts University who had independently developed K-12 engineering ...
Many of the coast redwoods (Sequoia sempervirens) grow to over 300 feet (91 m) in height. The forests on alluvial plains are almost pure redwood forest, but the forests on the slopes also contain Douglas-fir. [citation needed] Over 100 of the 137 known trees over 350 feet (110 m) tall—all coast redwoods—occur in Humboldt Redwoods State Park.
The California Tunnel Tree is the only remaining giant sequoia tunnel tree, while the other three surviving tunnel trees are coastal redwoods. [1] Today, tunnel trees serve as reminders of an earlier era in American tourism and as examples of the evolving understanding of the importance of conservation and tree preservation. [1]
