Located only 2.5 hours from Los Angeles, Joshua Tree National Park is the most accessible national park in Southern California. While it lacks the amazing vistas Yosemite and the massive trees of Sequoia, Joshua Tree's stark landscape is something you need to get out of the car and explore to really appreciate. I always love my time there, especially when I can camp and watch an amazing sunrise or just stare up at the clear night sky. You can see some of my favorite adventures here below.

Most of the campsites in Joshua Tree National Park are first come first served. If you are going on a busy holiday weekend then be sure to get there early so that you do not miss out on a spot. My favorite campground is White Tank as it is near Arch Rock. You can read more about the campgrounds here
