We return to Noe Valley for another tour exploring the arboreal richness of this neighborhood - but this time, the northern half of the neighborhood. For this tour, we start out at The Animal Company, in its new headquarters at 24th and Castro streets, and remain north of 24th Street, between Douglass and Vicksburg streets.

Today’s walk begins with an exceptional specimen on Castro Street, just north of 24th Street. The walk continues uphill, heads west on Elizabeth Street to Douglass Street, then north on Douglass to 23rd Street, and east on 23rd all the way to Vicksburg Street. At Vicksburg, the walk heads south to 24th Street, and then returns to its start at 24th and Castro, with a quick jog north on Noe for a special tree. This walk is roughly two miles 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 59. White arrows on the pavement provide directions whenever a turn is needed.
