A field guide for walking · San Francisco
Walk past the city's
flowering trees,
this august.
SF Bloomwalk routes you A to B (on foot only) past street trees that are probably in bloom right now — using the city's public tree census and seasonal flowering data for thirty-some common species.
How it works
01
Tell us where
Drop a start (and an end, if you have somewhere to be). Everything is bounded to San Francisco.
02
We check the census
We pull street trees from SF's public dataset along your corridor, then keep only the species that should be flowering this month.
03
Detour, gently
A bloom dial decides how far you're willing to wander. We re-route through the best flowering candidates, never doubling your walk.
