If you're talking about the NAVY'S PIERS and loading docks at San Clemente Island..
USUALLY NOT. The FIRST THING you need to do before running all the way there..
is CHECK FOR CLOSURES. There's a site..go to
San Clemente Island where it LISTS the dates and times of closures for all or which end/areas of the island. We've
fished way inside the big kelps on Pacific Star, BigGame90, many times..but NOT all
the way in by the landing piers. THAT, as in fishing inside the inner coves down from
the buildings...is ONLY when totally open and allowed. The site has a lot of info on
this. I'm sure the many guys on here with Private Boats can ADD A LOT MORE as to
WHERE and how they did inside the landing coves.
AS FOR FISHING IN CLOSE...pretty amazing what you get HAMMERED on in there sometimes
Everything from big Calicos, Barracuda, White Seabass, even Yellowtail..and of course
the infamous BAT RAYS are thick under that huge kelp forest..believe me..
