Black Diamond Mines Regional Preserve

Black Diamond Mines Regional Preserve is an East Bay park spanning more than five thousand acres.

I spotted what looked like an easy four mile loop. It was nearly seven, I guess all the .3’s really do add up. The loop we did was a mix of exposed sunny ridgelines and shady canyons. We went on a ‘cold’ day which was still high 80s and a nice sweltering break from the San Francisco fog.
