where are the giant redwoods
When you set out to take in the Giant redwood trees of California, pack your camera and head south to the parkâs Mariposa Grove. Conveniently located near Yosemiteâs south entrance, Mariposa Grove is home to the Grizzly Giant sequoia, a leisurely 0.8 mile walk from the main parking lot. The oldest known giant redwood trees in California are more than 3,000 years old. 2  The bark of Giant Redwood Trees can be as thick as 4 feet, and helps make them fire resistant. 3  In addition, fires actually help redwoods survive by wiping out smaller trees that would eventually take over.
