Sequoia & Kings Canyon National Park This dramatic landscape testifies to nature's size, beauty, and diversity--huge mountains, rugged foothills, deep canyons, vast caverns, and the world's largest trees. These two parks lie side by side in the southern Sierra Nevada east of the San Joaquin Valley. Weather varies a lot by season and elevation, which ranges from 1,370' to 14,494'. Sequoias grow at 5,000 - 7,000’, above usual snowline.
