Contra Costa County Highpoint Trip Report

Mount Diablo (3,849 ft)

We drove the road to the summit. I was surprised to see there was a hole in the floor of the observation tower in order to afford access to the true summit. Mount Diablo was used for surveying parts of California, Nevada and Oregon, so this summit is of historical interest, hence the hole. The tower is open Wednesday through Sunday, year round, staffing permitted. Plan on visiting when the tower is open in order to properly claim this one.
