Western Sierra Nevada
Among the mountains, massive giant sequoias thrive. While they are often shorter than coastal or giant redwoods, giant sequoias, also called Sierra redwoods, are typically larger and substantially outweigh redwoods. The largest living organism on Earth, the General Sherman tree, is a sequoia that stands more than 100 feet wide and is estimated to weigh 2.7 million pounds.
Yosemite National Park protects three ancient groves. Mariposa Grove, which reopened in the summer of 2018 after a three-year restoration project, is the largest with 500 mature giant sequoias. Located near the South Entrance, it’s also the busiest of the bunch. Tuolumne Grove is more remote and home to 24 or so mature trees. The Merced Grove east of the Big Oak Flat Entrance is similar in size to Toulumne, but visitors must hike 1.5 miles to catch sight of the sequoias and parking is extremely limited.
Sequoia and Kings Canyon National Parks offer some of the best spots to see the behemoths, including the General Sherman tree. Stand below it or take a free park shuttle in the summer to see its size from a distance. Grant Grove and Giant Forest house the largest sequoia groves in the park and are a must-see.
