San Bruno Mountain is one of the largest public open spaces in urban America.
Our programs provide opportunities for people to explore and restore the mountain's unique ecosystems.
Explore San Bruno Mountain's less-traveled canyons and learn about their history and ecology on this docent-lead hike. Paul's hikes are one of our most popular events!
THIS EVENT HAS BEEN CANCELLED DUE TO THE RAINY WEATHER. PLEASE JOIN US ANOTHER TIME!
Protect butterfly habitat in Owl Canyon by helping remove escaped weeds. Enjoy beautiful mountain and bay views!
Join a great group of dedicated plant lovers every Wednesday - there's always room for more!
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.
