This area consists of a few boarded up beach homes, two dumpsters, and a truck which contains radioactive waste transported there from San Onofre. There is a campfire here, located in front of a trailer.
The radioactive waste truck can be opened in order to spill the barrels onto Cottonwood cove below. This is for an optional part of the quest Eye for an Eye.
Cottonwood overlook appears only in Fallout: New Vegas.
