Join the Dune Defenders on San Bruno Mountain's ancient dunes! Volunteers will help improve the habitat of the rare and endangered San Francisco Lessingia plants by removing invasive species!
Volunteers will also enjoy a colorful (wildflowers!) guided hike on the dunes to learn about their fascinating cultural and natural history.
Parking is available on Thiers St and the dirt road next to the Hilldale School.
