Surprise! San Francisco has hills! And stairs! Lots of them! Which means you never actually have to go inside to exercise. There are loads of challenging spots with killer views, all available for free if you know where to go. When you’re looking to get outside and get after those glute gains, check out these picturesque local spots.

Lyon Street Steps

There’s a reason why this is the spot that everyone in the city loves for running stairs: million dollar views, surrounded by multi-million dollar mansions. This is the staircase where you chase the dream that if you keep working hard and kicking ass, you, too, can become a San Francisco billionaire. Want to amp up that workout? Add a set of burpees at each landing.

Twin Peaks

Sure, you’ve driven to the top, but have you ever thought about running or riding your bike up Twin Peaks? Round trip from Twin Peaks Boulevard to the summit is two miles of unforgiving hills, with an unforgettable view. Looking for a punishing 6-miler? Add nearby Mt. Sutro into the mix.

Filbert Steps at Telegraph Hill

If North Beach greenery is more your speed, try a hike up the Filbert Steps. Take the steps up to Coit Tower and back for a .5 mile loop. Access is on Filbert Street between Montgomery and Sansome, and there are some pretty sweet views at the top. If you arrive between 10 am and 5 pm, you can even get bonus steps climbing to the top of Coit Tower.

Buena Vista Park

At the oldest park in the city—yep, it predates GGP—you can follow both paved and dirt paths that twist and turn up the peak, where you’ll find a lovely view of the Bay and the Golden Gate Bridge behind St. Ignatius. This is an excellent option for exploring with your dog; there’s a dog run near the Haight Street entrance to the park.

The Vulcan Stairs

On Ord Street, off of 17th Street in the Castro, there are two staircases that most people in the city have never heard of. The more southern option, the Saturn Street Steps, is a frequent afternoon lounging spot for San Francisco’s famed wild parrots. The northern set, the Vulcan Stairs, houses the secret garden you’ve dreamed of finding. Lined by quaint cottages, the Vulcan Stairs give you approximately two blocks of steep climbing to set your heart racing. Want to keep going? Hit up Buena Vista Park or Corona Heights Park nearby for more jaw-dropping views.

Lincoln Park Steps

While the Lincoln Park Steps date back to the early 1900s, this Seacliff staircase on the western end of California Street got its mosaic makeover in 2010. On the ascent, runners can take in local artist Aileen Barr’s tile art design on the risers; from the top, there are views of Golden Gate Bridge, San Francisco’s downtown skyline, and the East Bay hills.

16th Avenue Tiled Steps

Another mosaic staircase, this time in the Sunset, the 16th Avenue Tiled Steps are located on Moraga Street between 15th and 16th Avenues. Aileen Barr (you know her from the Lincoln Park Steps) and Colette Crutcher designed the steps in 163 mosaic panels. Since this one lacks a nearby park, consider multiple heats up and down the staircase for your workout, or add a run to the Hidden Garden Steps.

Hidden Garden Steps

Also on the 16th Avenue, between Kirkham and Lawton, the Hidden Garden Steps round out our tiled-staircase trifecta. Designed by Aileen Barr and Colette Crutcher, installation wrapped on this beautification project in 2013. During the dry months of summer and fall, the Hidden Garden Steps offer visitors colorful florals that cease to exist in nature.

Even on these smaller staircases this one., it’s possible to get a workout to rival any boutique HIIT class in the city. Try this one from BodyBuilding.com if you need inspiration: with single leg hops, burpees, grapevines, and multi-step leaps, it’s guaranteed to get your heart racing and make you question why you thought staircase exercises would be a good idea.

Lands End

For those stunning summer spring and summer sunsets, head west to Lands End. The Lands End trail is just under three miles, (out and back), Runners in these parts are rewarded with views of both the Pacific Ocean and the Bay. While the route is mostly flat, there’s an optional set of stairs to torch your tush.

Sunshine can do you a world of good, so get outside and soak up some Vitamin D. Unsure where to begin? We’ve collected the nine points above into handy map right below.
