San Francisco's reputation for hills scares riders off — which is a shame, because the city grew a cycling culture precisely by solving that problem. Generations of riders have mapped the flat ways through: routes that thread valleys, follow the old streetcar grades, and string together the city's growing network of protected lanes and car-free streets. Ride SF the local way and it's flatter, safer, and far more fun than the elevation profile suggests.
The Routes: Where to Ride Safe
SF's most famous piece of cycling folk knowledge: a zigzag of quiet streets from Market Street to Golden Gate Park that dodges every serious hill by following the path of a buried creek. Officially signed, heavily ridden, and the connective tissue between downtown and the park. Learn it once and the west side of the city opens up.
JFK Drive went permanently car-free in 2022 by ballot measure, turning the main artery of Golden Gate Park into a promenade. Combine it with the park's other paths and you can ride from the Panhandle nearly to Ocean Beach with barely a car interaction. On Sundays even more of the park's roads close to traffic.
The classic. Ride the waterfront through Crissy Field on the car-free Bay Trail, climb to the bridge, cross on the dedicated west or east sidewalk (bikes are always separated from traffic), then descend into Sausalito and take the ferry back. The single most popular tourist ride in America, and genuinely safe the entire way.
The flat waterfront run from Oracle Park past the Ferry Building toward Fisherman's Wharf, continuing into Crissy Field. Watch streetcar tracks near the piers — cross them at an angle. The natural spine for any visitor's first SF ride.
The Mission's main cycling corridor and one of the busiest bike streets in the city, upgraded in recent years with protected lanes. Flat the whole way, connects to the Wiggle at Market, and delivers you to the best burrito density in North America.
Born in 2020 and made permanent on key corridors, SF's Slow Streets limit through-traffic on residential streets like Page Street (the Wiggle's western approach) and Sanchez. They're the low-stress way to cross neighborhoods the protected network doesn't reach yet.
The Group Rides: SF's Cycling Culture
Critical Mass
The ride that started a global movement — San Francisco's Critical Mass has rolled on the last Friday of the month since 1992. Unmarshaled, unpredictable, and a piece of living cycling history.
SF Bicycle Coalition rides & classes
One of the strongest local advocacy groups in the country, the SF Bicycle Coalition runs free urban-cycling classes and community rides — and is the reason much of the protected network exists. Membership directly funds more lanes.
The Marin roadie pilgrimage
Cross the Golden Gate early and you join the weekend migration: Hawk Hill's iconic climb in the Marin Headlands, the mellow Paradise Loop around the Tiburon peninsula, or the full pilgrimage up Mount Tamalpais — road cycling's Bay Area holy trinity.
Infrastructure & Safety
SF's network is a patchwork: excellent car-free spines (the park, the waterfront), a growing set of protected lanes (Valencia, Market Street — which banned private cars in 2020), and Slow Streets between them — but the connections still involve regular city traffic, and the hills push riders onto a handful of predictable corridors. Streetcar tracks, fog-slick descents, and heavy weekend tourist traffic on the bridge approaches are the local hazards.
Best Time to Ride
SF cycling is year-round — no snow, rare freezes. September and October are the warm, fog-free sweet spot. Summer mornings mean thick fog and cold wind at the bridge (bring a layer; it burns off by noon inland). The park and waterfront are busiest on weekends; early weekday mornings are gloriously empty.
