If you’re looking to camp in California, Sequoia National Park should be one of your top destinations. They have cabin and tent camping. I have stayed in both. There are trails galore and GIGANTIC trees bigger than your car. This beautiful setting is worth visiting year round and I recommend camping during the less touristy times in early Spring and Fall. You are near lakes, waterfalls, and an array of bodies of water. I recommend coming up the back end up the park for an easier ascent rather than via the 198. The 198 takes you up a steep, but beautiful, hair pin turn ridden road. If you get car sick easily, take the route through Fresno.
