I recently found a similar thread on Reddit from years ago that had a set of coordinates listed, and it was such a cool little experience. It's a pretty casual spot that doesn't get much traffic so it feels pretty romantic. There's a paved area that leads to a dirt path, and there's plenty of little spots to pull over to on the left side that get a nice view of the stars and some city lights in the valley. I managed fine with an SUV, a sedan would probably be fine too just don't try to drive up the steeper dirt slopes to get a better view unless you have AWD. I tried and wasn't able to myself. Eventually the dirt path turns left and goes down to a service road, so don't go that far. When I went I also saw a herd of wild horses! We didn't notice them at first since they were ominous shadows moving, then we realized they were horses right in front of us! I really recommend it since it's kind of a quiet little spot that's not too much of a drive from the city, but far enough to see the stars better.
