Just outside Sequoia National Park in Three Rivers, Kaweah Whitewater Adventures offers thrilling guided rafting trips on the Kaweah River. Fueled by Sierra snowmelt, the river delivers fast-moving Class III–IV whitewater in spring and early summer, making it one of California’s most exciting short-run rafting experiences. It’s a perfect high-energy counterbalance to Sequoia’s peaceful forest hikes and a great way to experience the power of the mountains up close.
