Upper Hawthorne Canyon, San Anselmo

Hawthorne Canyon Open Space Preserve

On March 4, 2024, the Marin Open Space Trust (MOST) permanently protected the scenic 9.4-acre Upper Hawthorne Canyon property in San Anselmo. MOST acquired the land and donated it to the Town of San Anselmo for an open space preserve, and also provided stewardship funds.

Nearly 100 community members donated more than $247,000 toward the property’s purchase and stewardship. Marin County Parks granted $100,000 in Measure A funds, the San Anselmo Open Space Committee donated $234,600 from Measure A funds, and the Town of Fairfax donated $12,000.

Just below Oak Springs Drive and adjacent to Fairfax, the property borders the Town of San Anselmo’s 22-acre Hawthorne Canyon Open Space Preserve purchased in 1999, as well as two other town-owned open-space parcels; with the preservation of Upper Hawthorne Canyon, 45 contiguous acres are protected.

Two dirt paths descend the Upper Hawthorne Canyon property’s grassland, connecting Oak Springs Drive with the lower preserve’s oak woodland landscape. The outstanding views from the property look out over the scenic hills of San Anselmo and Fairfax, with Mount Tamalpais and San Francisco Bay in the distance.
