This looks a lot like Gray Whale Cove State Beach in California, just south of San Francisco.
Your picture (while certainly 'photoshopped' to some degree) seems to have been taken from a similar viewpoint to the one tiny picture in image gallery on the California Parks & Recreation page for this location.
Whether or not this image represents a real location, there are several artefacts of image manipulation visible. In the top right there are interrupted lines visible. They resemble power lines to me, but either way, they have been clearly manipulated.
In addition, this error level detection algorithm shows high levels of manipulation in some areas, little manipulation in others.
As a result, I think it's fair to conclude that this is, as is, not a real location.
While I cannot identify the specific beach, that area looks very much like the California coast, especially the Devil's Slide section just south of San Francisco, in its ruggedness and the presence of the ice-plants, the whited rock, the fog, and the road (which would be Route 1) running along the cliff.

The landscape in your picture is considerable greener than Northern California ever gets, but if you like dramatic cliffscapes, this is the place to visit.
Edit: Hahaha. Other people have identified your beach as Gray Whale Cove State Beach, which means it is about 20 feet south of the bottom edge of the photo I selected, more or less at random, to illustrate what the coast looks like. The promontory in the midground of the original picture is in the foreground (at high tide) in mine.
