Alabama Hills is a popular area to see the beauty of natural rock formations. This is BLM land so there's no campground amenities.  However you can camp here for free in many dispersed locations.  Just look around and look for spots that you can park and camp at. There are plenty of sites back into the rocks. There's cell service where the main road starts but not much after that. This is a great place to view the Milky Way and watch the sunrise. This is a great place to go rock climbing.
