Why go
A longer protected or low-gradient route is often easier than a short line drawn across Russian Hill, Twin Peaks, or another steep interior ridge. The Embarcadero and northern waterfront provide relatively level riding, while the Golden Gate Bridge opens a dramatic connection toward Sausalito and Marin.
The full story
The Embarcadero and northern waterfront provide relatively level riding, while the Golden Gate Bridge opens a dramatic connection toward Sausalito and Marin. Golden Gate Park offers another useful east-west corridor. Between them, elevation and traffic can change quickly. Choose routes from current city bicycle maps rather than relying on the shortest driving directions. Bridge paths may switch sides or carry heavy pedestrian traffic, so slow down and follow posted rules. Bring a layer for fog and wind, secure the bicycle carefully, and plan the return before committing to a long descent. Riders heading to Twin Peaks, the Presidio hills, or Marin should compare distance with climbing. Ferries and transit can provide a sensible one-way alternative when service permits bicycles. A careful reading of Cycling in San Francisco also places the subject within its surrounding districts, transport corridors, and named landmarks, making the resulting route more coherent.
