This is a little beach a few blocks from my house. Kind of hard to believe, the sidewalk is just on the other side of those cliffs on the left. It's a nude beach, and it's pretty much protected from prying eyes, but not completely. It's called 2222 beach because that's the house number across the street from it.
The beach doesn't even exist during the winter, but the sand returns starting in the spring, and if it isn't too full of kelp and flies, it's nice all summer. There are kelp beds out a ways in the water, and you can swim way out to them, naked, and hang out in the kelp. Of course, you're completely freezing when you get back, but that's OK.
