What I've done before, and what I've just now scheduled for Sept 15, is to take a walk down the Pacific coast. In past years, I've walked from Pacifica to around Half Moon Bay. It can be done in one long day, or, better yet, over a few days, staying in hostels on the way. There is some beautiful coastline, very fine beaches, excellent mountain trails with wildflowers and breathtaking vistas, and, most importantly, a chance to get the hell away from it all. The last couple of times I've done it, it's restored me to sanity. Ten more days. I can hardly wait.
