Fishing from the Harbor

I figure you guys would know better than I. I just started pier fishing a few years ago, but only make it out a handful of times a year. I guess I would call Dana Point/San Clemente my go-to's. When in Dana Point Harbor, are you allowed to fish off the railings that aren't the pier area? Like behind the Henry Dana Statue, etc. I know you can go out to the jetties, but wanted to see where else was available.

Thanks in advance!
