Come here to witness some of the most majestic sights you’ll find not just in California but anywhere in the world. These adjoining parks are where you’ll find 14,494-foot Mount Whitney—the highest peak in the Lower 48. And while there are taller trees elsewhere, the General Sherman Tree is the biggest on the planet by volume: 275 feet tall and with a stout, 36-foot-diameter base. You truly have to see it to believe it, and it is easily reached via a short, paved trail in Giant Forest.
