OverviewBriones Regional Park is a lovely area of ranchlands, valleys and rolling hills with ponds and wildlife in the SF Eastbay. These 2 little peaks are the high points in the park. I decided to put them together on one page because they can easily be done on the same dayhike and on their own don't have much significance. Briones Peak (1,483') has trees obstructing the southeast views but outstanding views north out over San Pablo Bay and Suisun Bay west of the Sacramento River Delta as well as Mt.Diablo to the east. Treeless Mott Peak, 1,424', is more centrally located in the park and has better all around views.
This peak is named for William Penn Mott (1909-1992) one of the most influential directing founders of the California Parks Foundation who lived in the Bay area most of his life.
