This is one of our intermediate stops if I'm going on a weekend trip to Mammoth. There are a pretty substantial amount of off-road/mtb trails in this area, if that's your thing. Also, you might get the stray hiker trying to make it to the Mount Whitney trailhead.
Desert landscapes aren't usually my thing, but there's plenty of space. I'd avoid in the summer unless there's something you really want to do here - it got fairly hot even in March. Also, it's free, so for the price I can't really complain. Just pack in/pack out!!
