This is just a few parking lots that overlook the valley and gives a view of the city skyline in the distance. Several others were also sleeping in their vehicles along the road and in the parking lots, so you won’t be alone. There were two others in our lot that stayed the night too. The view is gorgeous in the morning sunrise!
That being said, it did seem like maybe a teen hangout or something - cars did flow in and out occasionally through the night until around midnight, so that wasn’t great but not awful either. I’d use it again if I needed it as it’s hard to find free places to sleep with a great view like that when traveling through cities.
