Sun, May 3, 9:00-12:00pm

The 162-acre property in the foothills of Sonoma Mountain is protected by a conservation easement made possible by your Sonoma County Agricultural Preservation and Open Space District (Ag + Open Space) and the California Wildlife Conservation Board. The property is managed under a partnership with the landowner and Sonoma Ecology Center, to protect the Preserve’s unique plants, thriving streams, and wildlife habitat.

This outing is a beginning-level walk over gently sloped land. Most of the walk is through grassland, generally not on trails, so the footing can be uneven. The walk crosses a few small creek channels, which sometimes have shallow water with stepping stones.  There is no charge for this outing, which is made possible by the voters of Sonoma County who fund the work of Ag +Open Space with a quarter-cent sales tax.

Please note that these popular walks fill to capacity on a first-come, first-served basis every year, so early registration is encouraged! Walks will go on in light rain, but heavy rains will cancel the walk.

Directions and day-of-contact information will be emailed upon registration.

For additional information or questions about the outing, please contact Tony Passantino at (707) 996-0712 ext. 124, or
