Diablo MX Ranch (Sand Hill Ranch)

Diablo MX Ranch in Brentwood (originally Sand Hill Ranch) closed to the public in 2023 after 50+ years of continuous operation. The property is retained in this directory for historical reference and regional motocross record.

The 50+ year operating heritage made Diablo MX Ranch one of the longest continuously-running motocross facilities in Northern California. During operating years, the property was the East Bay's go-to practice facility, a hillside main track plus a PeeWee loop just east of the 580/680 split, the kind of geographic position that made it genuinely accessible to a substantial Bay Area rider population.

The hillside main track was the property's defining operational feature. Real elevation variation built into the layout used existing East Bay topography rather than relying on imported and built-up jumps for terrain interest. The dedicated PeeWee loop separated younger riders from main-track traffic for the family-friendly safety design.

The 2023 closure created a significant gap in the regional East Bay and broader Bay Area motocross facility inventory. For local riders who used Diablo MX Ranch as their home destination, active alternative facilities in the broader Bay Area region include:

Carnegie SVRA in Tracy (Central Valley access, the closest active alternative for many East Bay riders).

Argyll MX in Dixon (broader Bay Area access, famous for the adobe clay surface that builds serious technique).

Metcalf Motorcycle County Park in San Jose (South Bay access, the everyday riding spot for Santa Clara Valley local riders).

For local riders in the broader East Bay and Bay Area region seeking active motocross facilities, refer to the broader California regional motocross listings for current operating windows and access details. The Brentwood-Sand Hill Ranch heritage closure marked the end of a 50+ year regional motocross destination.

The property is retained for historical reference and to preserve the regional motocross record.
