California is known for its redwood and sequoia forests, home to some of the tallest and oldest trees on Earth.

The state is famous for its coastal redwoods (Sequoia sempervirens) found in the northern part of the state, and the giant sequoias (Sequoiadendron giganteum) found in the Sierra Nevada Mountains. These trees are remarkable not only for their size but also for their longevity, with some of the largest sequoias being over 3,000 years old. California's redwood and sequoia forests are protected in national and state parks, such as Redwood National and State Parks and Sequoia National Park, attracting millions of visitors each year.
