Though I know Joshua Tree isn't in Orange County, it is about a one and a half hour drive, so I wanted to post something about it.
Joshua Tree National Park is a pretty cool place. Filled with all kinds of funky trees, beautiful stars, and rock mountains, it really is a power spot where you can go and rejuvenate from all the daily stress. The Joshua Park National Park is a great hiking/camping/rock climbing spot, and you can walk through a variety of trails there.
We got to visit Joshua Tree this summer, and hiked through all kinds of trails in 106 degree weather. It was pretty hot when we went, so you will definitely need water, sun block, and a big hat to keep you away from the sun. You might want to go check out a swap meet in Orange County to buy a big farmer's hat for $4.
When we went, we stayed at the Spin and Margie's Desert Hide-a-Way. It was a cute little bed and breakfast (no breakfast though) type of hotel with only five rooms. The owners at this hotel did an awesome job with their hotel, and it surely is a place where you can re-energize from the daily hustle and bustle.
At night, the stars were amazingly beautiful since there really aren't any city lights in Joshua Tree. You can see all kinds of stars that you never knew existed above us. We went during a time when there were a bunch of shooting stars, so got to see a few of them while we were there.
If you're feeling stressed, or just want to get in touch with nature again, Joshua Tree National Park is one great place you go and check out. Only about an hour and a half from Orange County.
