Elephant Seal Boadwalk - San Simeon, California
Just up the road (or down depending on your direction) from Hearst Castle is the Elephant Seal Boardwalk, overlooking the very busy Piedras Blancas Rookery.
Taft Point - Yosemite National Park
It's an incredible spot, one of the most beautiful places I've ever seen, and despite my fear of heights I enjoyed sitting at a safe distance and enjoying the view.
