California is blessed with many fine state parks and this is one of them and the largest in the state. It has a variety of areas from Badlands to Sandy washes to mountain high desert. Some people would call it the Colorado desert or the Sonoran desert you're almost on the western fringes of that area with Palm Springs. Basically you're in a desert environment so you have to be aware of having your own gear to survive if you need to. Common sense, you need to wear sunscreen and bring plenty of bottled water available and some sleeping gear in case your car gets stuck or broke. I would also recommend a basic first aid kit and of course some kind of cactus kit including needle nose pliers tweezers maybe duct tape to remove cactus needles.
