From St. Helena pass to Table Rock above Napa Valley.
Was heading up to visit some friends around Cobb Mountain over the weekend. Highway 29 goes right over the pass next to Mount St. Helena (4,343'). Just across the road is the 5 mile round trip trail to Table Rock (2,462'). This is a big rolling volcanic outcrop up by the Palisades above Napa Valley with some pretty cool views.
