[NOTE: we chalked a new tour in the Glen Park neighborhood yesterday (10-25-20); that tour should be up on this site very soon!]

We were treated to another gorgeous autumn day for this walk through the “Transmission” neighborhood, with a focus on Fair Oaks, one of the most desirable streets in the Mission/Noe Valley neighborhoods. A warm climate with underground streams likely, this neighborhood is filled with an array of notable trees, including a few seldom seen in the City. It’s a short walk, but a rich one tree-wise.

The walk begins on Dolores and 22nd streets and heads east on 22nd to Fair Oaks Street, then south on Fair Oaks to 24th Street, east on 24th to San Jose Avenue, north on San Jose to 22nd, and then west on 22nd to Fair Oaks, a block from the tour’s start. This walk is a little over one mile long.

Numbered trees are labeled with common and scientific names and country of origin, all written in white chalk on the sidewalk; accompanying numbers, in blue, run from 1 to 46. White arrows on the pavement provide directions whenever a turn is needed.
