Want to go to a place where there are hundreds of waterfalls, trees as tall as skyscrapers, and towering slick rock mountains just begging for climbing? If so, you'll love visiting Yosemite National Park. This stunning park is located in California. It is where the giant sequoias live, some of the world's largest trees. The biggest, Grizzly Giant, is 30 stories tall and thousands of years old. Among the park's many types of animals are rare great gray owls and endangered bighorn sheep. John Muir loved this place. So did President Theodore Roosevelt. Ever since they helped make Yosemite a national park, millions of visitors have come to enjoy its natural beauty.
