Castlewood Country Club - Valley Course

Castlewood Country Club Valley Course is an 18-hole facility in the Castlewood area of Pleasanton in the Tri-Valley region of eastern Alameda County. The Castlewood area is in the Sunol Ridge terrain above the Amador Valley floor, in the foothill zone between the flat Pleasanton residential core and Pleasanton Ridge Regional Park above. The Tri-Valley region has developed substantially since the 1980s as the Interstate 580 and 680 freeway corridors started operations access to the outer East Bay communities from the Silicon Valley and San Francisco employment markets.
