Yosemite National Park lies east of San Francisco in the Sierra Nevada and offers visitors a varied landscape of deep valleys, vast meadows and groves of giant sequoia trees. Ninety-five percent of the park is designated as wilderness. It's best known for its spectacular waterfalls, which are at their most robust in spring.
FOR THE RECORD:
National parks: A previous version incorrectly said that Yosemite National Park lies west of San Francisco. The park is located in the Sierra Nevada east of the city.Mark Boster / Los Angeles Times
