Warning: not for the faint of heart! Climbing six percent grades up to the second oldest National Park is well worth the effort, and where you'll finally get to see the world's largest (by volume) and second largest trees! There's also a special unrehearsed appearance by a large, furry animal and several tiny ones. Kings Canyon is equally awesome with exceptionally twisted cliff-hugging roads offering panoramic views around every bend. Rust and tan-colored boulders in the foreground are accentuated by huge spiked yucca plants. Eventually you'll reach the bottom, where the journey takes you up along the whitewater rapids of the King River. Every mile is enchanting! 80 minutes in length.
