Santa Cruz Wharf is adjacent to the Boardwalk and Main beach. It is a very long pier with lots of restaurants, shops and  sea lions at the end of the pier, and on one of the boat landings on the left side near the beginning.  Very amusing.

From here you can go on a whale watching boat or on a fishing expedition..  You can also fish from the wharf, and there is a bait shop. There is also a very good fish market.  As you can imagine, the fish is VERY fresh.
