Volunteer to save critical grasslands at San Bruno Mountain Park. Join the SSF Weed Warriors for fresh air and exercise and help them weed on the south slope of mountain.
Do habitat restoration work on the mountain, either doing site preparation-including weeding-or planting California natives.
Docent-led hikes hosted by San Bruno Mountain Watch are a unique experience for people to learn about the mountain's ecosystem and to become involved in its protection.
These free walks are led by docents at Edgewood Park and vary according to what's in bloom. The walk covers about 3 miles, at a moderate pace, with frequent stops.
