For almost 100 years, Diablo Country Club has been a true test of golf, and recognized as one of the most desirable courses to play in the San Francisco Bay area. Originally designed by Jack Neville and William Watson, these men went from Diablo to projects creating Pebble Beach Golf Links and the courses at the Olympic Club. The design, like most pre-WW1 courses, showcases well-bunkered, small greens and fairways lined with majestic Oak trees, whose ages are measured in hundreds of years. The course also features stunning countryside, including the Las Trampas Range and spectacular vistas of Mt. Diablo. Playing at a par 71, the course offers the Macdonald Smith Championship tee measuring 6,766 yards, a 73.8 rating and slope of 139. Diablo has served as host to Professional Exhibitions, the Northern California Open Championship, USGA Amateur Championship qualifiers and US Senior Open qualifiers.
