Sorry, I may be reading too much into your question and not sure if your question relates to camping in AH during Covid-19 or just booking there in general. If it relates to camping during Covid you’ll want to refer to California Department of Public Health guidelines. If it is general camping e.g. pre-Covid I would say NO we have never felt discouraged to camp in the Alabama Hills. That said, the BLM managers do make regular (almost daily) trips around the Hills to ensure that folks don’t park in inappropriate places and respect the flora, not parking on it. We have been encouraged to use Tuttle Creek CG, it having water, and rest rooms, but we have never been strongly discouraged to stay in the Hills. Hope this helps.
