In Sequoia National Park stand the largest trees anywhere. The giant sequoia groves are a must-see on any vacation in California. There are seventy-five groves containing gigantic sequoias that are often over 3,000 years old. The sequoia is an awesome example of nature.
When visiting Sequoia National Park, be sure to see the Boole Tree, standing 269 feet tall with a circumference of 112 feet. It's on the Hume Lake Road just north of Converse Mountain. You will find some great fishing here as well as trails for biking and hiking. The scenery is fantastic. In the summer, you can take ranger-led walks and evening programs. Take a bus tour or go horseback riding. There's plenty to do.
Camping is a favorite here, and you'll find campgrounds in the park that are operated by the Park Service. No hookups for RVs however. There are more camping facilities in nearby national forests. You'll find the exact right one for you.
It's quite a drive from Yosemite (about 6 hours) but certainly worth it! Take CA-140 to CA-41 to the exit onto CA-99 south. You'll take exit 97 towards Sequoia Park and follow the signs.
