Yosemite National Park - General Park Information

Not just a great valley, but a shrine to human foresight, strength of granite, power of glaciers, the persistence of life, and the tranquility of the High Sierra.

Yosemite National Park, one of the first wilderness parks in the United States, is best known for its waterfalls, but within its nearly 1,200 square miles, you can find deep valleys, grand meadows, ancient giant sequoias, a vast wilderness area, and much more.

Yosemite receives most of its precipitation in the months of January, February, and March. Summers are typically warm and dry. Spring and fall are transitional months, when warm, sunny days can suddenly become stormy. Clouds can build up during the summer to produce spectacular thunderstorm activity.

Yosemite National Park is open 24 hours per day, 365 days per year, and no reservations are required to visit. However, the Hetch Hetchy Entrance Station is open only during daylight hours (approximately) and some roads are closed due to snow from around November through May or June.

Nearly 95 percent of Yosemite National Park is designated Wilderness. Wilderness is a special distinction granted by Congress protecting land from further development. The best way to experience the 1,100 square miles of the Yosemite Wilderness is to explore it first hand.
