An absolute marvel of a structure. The views are amazing in all directions. The walkway apparently runs two miles from one end to the other. If driving, the speed limit is 45 mph (no more than that). It's usually packed with pedestrians and traffic due to its popularity and only means of passage from the Marin County side to San Francisco. Travel from San Francisco to Marin County is free but there's a toll charged every time you travel back into San Francisco.
