Is Marina safe to ride a bike?
This page covers traffic crashes, not crime. We don't rate neighborhoods as safe or unsafe: crash counts can't say how risky a street is, and busy streets have more crashes partly because more people use them. What the records show: 44 bike crashes were reported in Marina from 2021–2026, 5 of them serious or fatal. The most were at Bay St & Laguna St (7). 57% were side-impact crashes at junctions (drivers pulling out or turning across). 20% happened after dark.
Marina here is one of the Analysis Neighborhoods the City of San Francisco uses for its own statistics, built from Census tracts; its edges may differ from where residents put the neighborhood.

Nearby neighborhoods in San Francisco
Source: California Crash Reporting System (CCRS), 2021–2026. A crash counts toward the neighborhood whose outline holds its point. 43 of the 44 crashes here had no coordinates on the report and were placed at the intersection its street names give. Reports with neither coordinates nor usable street names aren't on the map, so these numbers are lower than the real total. Busy streets show more crashes partly because more people use them.
