Drove here and stayed over night near the Natural Bridges beach. Lots of other vans and RVs along the street. There are areas with sign saying no overnight parking, we just found a spot along the street without those signs. Some light traffic during the night but overall slept well and felt safe. The area was filling up with parking early morning by hikers/bikers but we moved close to the beach instead.
