Sonoma Mountain Preservation
SMP's mission is to preserve Sonoma Mountain’s scenic, agricultural, and natural resources by cultivating a sense of place, engaging people in the landscape, and inspiring them to become mountain stewards.
Our hike volunteers are certified naturalists, experiential educators, and passionate about the land.
You all help this process along every time you hike the mountain, gift the book Where the World Begins: Sonoma Mountain Stories and Images, or volunteer with us.
