Rock Hudson is most often associated with Newport Beach , especially the yacht harbor and Lido Isle area, rather than a single widely confirmed “beach near LA.” A recent photo caption also places him on his sailboat in Newport Beach, and another source describes him around the yacht harbor there.

What’s known

  • Hudson had ties to the Newport Beach area, which comes up in accounts of his leisure time and boating.
  • I couldn’t verify a single beach he “frequently went to” from the available sources, so Newport Beach is the best-supported answer here.

Quick scoop

If you were thinking of a famous Southland beach hangout, the strongest match from the sources is Newport Beach. It’s not Los Angeles proper, but it’s the clearest nearby coastal spot connected to Hudson in the material I found.
