Sequoia and Kings Canyon National Park is truly a land of giants, home to majestic mountain peaks, an immense crystal cavern, the world's most enormous trees and a diverse array of activities for every season. Spring is the ideal time to visit the General Sherman Tree, the largest tree on the planet, while summer offers the perfect weather for a hike or a Crystal Cave tour. Fall colors light up the Big Trees Trail and winter snow makes for great adventure at the Wolverton Snowplay Area.
