Sequoia National Park from start of High Sierra Trail
29 km, 1583m up
It's quite relaxing to walk in the shade of majestic sequoias, so you mind consider to stay longer than a day for an easy walk.
I connected the walk with a start of High Sierra Trail and that make the one day trip quite long, but enjoyable.
Do not leave any food in your car. Black bears might try to get in and damage it. There are food lockers around.
