Layer up and visit some of SF’s greatest hilltops. If you’re not familiar with SF weather, be sure to bring your windbreaker, a scarf, 3 extra layers and maybe someone to cuddle with. There are a total of 44 hills in San Francisco, and here we have come up with the top five tops to drool over (though there were many runner-ups!) and to make your leg day a bit more scenic. Disclaimer: photos below represent San Francisco on a rare sunny day, best not to make the trek if it is foggy out.
