hey charlie, the most reliable spot in carpinteria that i know of is La Conchita, which is just on the southern part of carpinteria. as you drive south on 101, go past carpinteria towards ventura. you'll see the oil pier up ahead and you can park along side the freeway on the right hand side.

its a good spot for perch and corbina, especially at high tide. i've had the most success on the opposite side of the beach from the oil pier (i.e. the northern side of the beach, towards the rocks). hope that helps, best of luck.
