Mile Rock beach offers great scenery for beautiful maternity photography in San Francisco. It is a bit of a hike to get down to the beach but it has an absolutely spectacular view of the water, rocks and ridges. The crashing waves make for cinematic images and there is also a pretty wooded path leading down to the beach so you can squeeze in two locations at one stop. This is one of the best maternity photography spots in San Francisco as it is very romantic, natural and creates a striking scenery for your backdrop.
