Join Chuck Heimstadt and Loretta Brooks to explore the less-visited south slopes of San Bruno Mountain. This area features bright landscapes of large areas of grasslands critical to our resident endangered butterflies and some plants on the CNPS watchlist, such as coast iris, coast rock cress and San Francisco wallflower. We may also see onion, fritillaries and butterfly host plants: silver bush lupine and California golden violet. In addition, we’ll see Niebla lichen, which occurs only in the fog belt of the Californian coast, from Mendocino to Baja.

Since there are only fire roads and weeding trails on this side of San Bruno Mountain, the going can be difficult on steep and rocky slopes. Please be sure to wear sturdy footwear, as this area is really only for the adventuresome. We should have time to stop at the top, so bring a snack or lunch. There are no restrooms per se on the mountain, except in the parking area.

RSVP via email is required to join the hike. No drop-ins please and space is limited. To RSVP, please email Chuck and Loretta at This email address is being protected from spambots.
