Just a mile south of San Francisco, San Bruno Mountain is one of the largest public open spaces in urban America. Our programs conserve and nurture the mountain's unique ecosystems - home to 13 rare and endangered plants and three federally listed endangered butterflies.
Maintain a native garden with the Guadalupe Valley Stewards and help improve frog habitat!
Join this great group of dedicated plant lovers every Wednesday - there's always room for more!
Enjoy an inspiring presentation by David Nelson on the successful grassroots activism that saved the mountain and the bay! July 26th, 5:30pm-8:30pm
Don't miss wildflowers on the south slopes! Join the SSF Weed Warriors for their restoration work on the Mountain's south slope – and get some exercise! The non-native invasives are a constant battle so we need all the weed warriors we can get! Only heavy rain would cancel - so come prepared. Friday and Saturday 9am to noon.
David Schooley, founder of San Bruno Mountain Watch, will lead hikes into Owl and Buckeye Canyons on the 4th Saturday of each month. Be sure to sign up early - space is limited!
