Native plant expert Gregg Weber leads this trip to a floristically rich area of
Briones Regional Park. Toyon canyon trail descends 300
feet, to the creek, and a 300 foot elev gain follows.
We will see unusual plants such as Western viburnum, bent-flowered fiddleneck,
tufted poppy, Mount Diablo sunflower, and Eucrypta, plus many more familiar plants such as silver leaf bush lupine, coyote mint, Mules ears, pipe stems, hop tree, dutchmans pipe, and osoberry.
We will return to the cars at about 3pm.

of Briones Road and park on either side of the road. For the
Pinole/Martinez area, just proceed down Alhambra Valley
