Take advantage of the healing powers of nature while exploring diverse ecosystems on Sonoma Mountain. SSU Naturalists will lead you on a tour of this university education and research site, and give you insights into the ways we can work together to restore regional landscapes. Activities will be subject to change based on the most recent guidance about COVID safety.
SSU Student and Community Naturalists
University students and community docents will be your guide. Our guides are trained in natural history of the mountain and interpretation of preserve programs. They will lead you on one of many trails into this 450-acre preserve on the shoulder of Sonoma Mountain. Hike options include visits to the headwaters of Copeland Creek and spectacular vistas of the Santa Rosa Valley and Valley of the Moon.
We will meet in the Osborn Preserve parking lot. Trail groups leave promptly at 10 A.M. to explore different areas of the preserve, learning nature observation skills and knowledge along the way, as well as ways to take this new information back home and take action. Groups will break for lunch on the trail, and return to the parking lot at the end of the hike by 2 P.M.
Hikes take place each Saturday from April 2 - May 7
