It's not really a beach, but a stretch of ocean where the monster waves break. If they get big enough, world-class surfers have 24 hours to get there for the surfing competition. The rest of the year, there's not much to see.

A scenic beach formed at the intersection of San Gregorio Creek and the Pacific Ocean. The sand is often strewn with driftwood.
A nice beach with wide sand lots of gently-sloping sand at the base of high sandstone bluffs. The small lagoon faces onto roaring surf.
We're not talking about the Pebble Beach down by Carmel with the famous golf course. This one is much smaller and less-known. Instead of the usual sand found along this stretch of coast, Pebble Beach is covered with small stones, making it a bit of a different place to experience the ocean.
Dogs are allowed here, as long as they stay on a leash.
If you're looking for some of the best tidepooling on the California coast, Fitzgerald Marine Reserve is the place to find it. With lots of craggy rocks just below the surface, it's almost like a giant aquarium at low tide.
The big attraction here happens in the winter, when the female elephant seals come ashore to have their pups, followed by the males who bellow and fight, causing quite an uproar. The rest of the year, the beach is pretty but unremarkable.
You'll find two highly-rated beaches in San Mateo where clothing is optional and you can bare it all.
