If you plan to visit Sequoia National Park, consider the desired entrance. There are two options, CA 198 through Three Rivers, where we stayed, or CA 180 via Squaw Valley. The drive time on CA 180 from the Big Stump Entrance to General Shermans Tree parking is about 30 miles and will take an hour. The advantage of this drive is you will not have to deal with the twists and turns and steep drop-offs provided on CA 198. Your nerves will thank you.
