San Bruno Mountain is one of the largest open space parks within an urban environment in the United States and a refuge for dozens of rare and endangered plants and animals. San Bruno Mountain Watch emerged from the grassroots movements working to save San Bruno Mountain in the 1970s. Through guided hikes, educational programs for schools, community-based ecological restoration events, digital learning resources, and our native plant nursery, we educate the community about the remarkable natural and cultural history of San Bruno Mountain and engage people of all ages in protecting and restoring its native species and habitats.
