Sequoia and Kings Canyon National Parks

Birds flutter around a 250-foot-tall sequoia tree as a bear and her cubs walk along the forest floor past the tree’s enormous trunk. Welcome to Sequoia and Kings Canyon National Parks. Nestled in California’s Sierra Nevada mountains, these neighboring parks feature some of the tallest trees in the world. The diameter of the largest one here, dubbed the General Sherman tree, is bigger than a basketball court!
