Drone footage and handheld camerawork show the area of South Los Angeles' Sunken City near Point Fermin.
The area is named Sunken city after a natural landslide occurred in 1929 sending many homes into the sea.
The filmer, Graham Whatmough, explained: "Our team went to explore the famous Sunken City off the coast of San Pedro, California.
"This location is a quick drive south of LA, there is plenty of parking there and lots to do.
"You will find the ruins of what was once a fancy oceanside neighbourhood.
"We cannot recommend that anyone go there because of safety hazards.
"If you decide to go, do so at your own risk.
"We flew our Mavic Air 2 drone around the area one day to scout it.
"We analyzed the footage that evening and returned the next day to do some exploring on foot."
