Borges Ranch Flowering Plants

April 30, 2004

This year was cold and wet so the wildflowers are springing up two to three weeks later than normal. Our walk took us up the steep hill (south) at Old Borges Ranch, left through the gate and into East Bay Regional Park District land by going through the second gate. Here the road forks and goes left down to the bottom of the hill. Option 1 is to stop and turn around and come back at the picnic table. A second option is to continue up this road to the left, turn right at the first road switchback and continue up the steep hill until you see the foot trail off to the right and take that to the summit road. Here you can retrace yur steps or follow the road back to Borges Ranch.
