The 24 Best Things to Do in San Francisco

"Horses and carriages long had trouble conquering San Francisco's steep hills, and so in 1873 the cable car system was born—three lines of the original eight remain today. They are a symbol of San Francisco, the world's last manually operated cable car system, and one of the city’s most popular attractions. An estimated 9.7 million people hop aboard each year–the vast majority are tourists, but some residents still use these moving monuments to crisscross the city, just as was intended more than 150 years ago. Riding is a blend of an open-air bus and a slow-moving roller coaster. When you board, you'll either sit on the wooden benches for a more comfortable ride, or seek thrills and stand on the car's exterior, gripping the poles as the car moves up and down the steep streets of San Francisco." - Kimberley Lovato, Carey Jones
