Living here in the Bay Area, we are blessed with a variety of hilly rides though the forest and more. But there are four key peaks to ride up that I'm calling the "Big Four Bay Area Summits": Mt. Hamilton at 4,265 ft Mt. Diablo at 3,849 ft Mt. Umhunhum at 3,489 ft Mt. Tamalpais at 2,579 ft All of these can be ridden from near sea level to the summit so the elevations at the summit are aligned with the total climb, but not the same. This makes them a 'clean' achievement to ride to the top. Note: Some include Mt Saint Helena in the far North Bay but I'm going with the ones you can see from the main Bay as prominent, independent peaks.

Many of them are taller than Mt Tamalpais (Black Mountain for example at 3,747 ft), but arguably none have the same prominence. ( See a full list here ) So, why am I writing about this now?
