The Sequoia National Forest in amazing. Once you enter the park, you have to drive for about 30 minutes up a very windy, narrow mountain road. But it is totally worth it. At the top of the mountain are massive trees that make you feel tiny in comparison. There are several hiking trails, a museum/gift shop, and informational plaques all over. There are plenty of photo opportunities.
I would recommend using the bathroom facilities once you enter the park before making the drive to the top and use the bathroom again for the car ride back down, especially if you have small kids!
