Sequoia & Kings Canyon National Parks

Huge mountains, rugged foothills, deep canyons, vast caverns, and the world’s largest trees exemplify the diversity of landscapes, life, and beauty here. Explore these pages to plan your visit or to learn about the plants and animals here and the threats they face. Ancient giant sequoias may seem invincible, but they, too are vulnerable.

Weather & conditions

Because of the extreme elevation range in the parks, weather conditions vary widely between areas. In summer, the sequoia groves have comfortable temperatures and the foothills are hot and dry. Snow lingers on high-mountain passes well into summer. In fall, conditions can range from summer-like to winter-like. Winter brings snow to sequoia groves and rain to the foothills. Be prepared for tire chain requirements. Spring is a great time to hike in the foothills and snow begins to melt at higher elevations.

What this latitude gives you

From 36.7° north, anything above declination +53.3° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -53.3° never clears the horizon at all.

Astronomical darkness lasts through every night of the year here, including midsummer, which makes this a rare site for a June or July imaging trip.

We do not hold a measured Bortle class for this site, so treat the sky as unknown until you have taken a reading of your own.
