Mitchell Canyon, Mt. Diablo State Park

RSVP opens April 1. Please sign Waiver for Marin Chapter 2024.

Mitchell Canyon is one of the wildflower “hot spots” in the Bay Area. This walk will be slow and easy, about 2 miles in length total, three-fourths on the Mitchell Canyon fire road and one-fourth on the single-track Globe Lily Trail. Please bring your lunch. After the walk, we will eat at the picnic tables in the shade near the visitor center.

We expect to see the rare (1B.2) Mt. Diablo fairy lantern (Calochortus pulchellus), along with many other spring wildflowers, hopefully including goldenbush (Ericameria linearifolia), broomrape (Aphyllon fasciculatum), blue witch (Solanum umbelliferum), virgin’s bower (Clematis ligusticifolia), colonial onion (Allium unifolium), Sacramento Valley buttercup (Ranunculus canus), yerba santa, wallflowers, blow wives, ookow, silver bush lupine, and more. If we’re lucky, we’ll also see the butterfly mariposa lily (Calochortus venustus), although we may be too early for that one. And looking up, on the slopes of Mt. Diablo, we’ll see stands of beautiful gray pines (Pinus sabiniana).

The Mt. Diablo Interpretive Association publishes a wonderful online wildflower guide here: https://www.mdia.org/wildflower-guide. In addition, along the fire road there are ten numbered markers, which are described in this downloadable Mitchell Canyon Trail Interpretive Guide.
