Santa Ana Mtns
Dirt Bike Routes

The Santa Ana Mountains sit between Orange County and the Inland Empire, the Main Divide country about an hour from LA. These are mostly plated dual-sport and adventure roads, headlined by the ~35-mile North Main Divide over Saddleback. (For green-sticker OHV riding, the Cleveland's Wildomar OHV area sits on the southeast edge of the range, a separate staging-based trail system not detailed here.) Route geometry and elevation are pulled from the Forest Service's official travel maps and public terrain data.

Ways to string these routes into a full ride instead of a single road. Mileage is a rough composite; segments overlap and connect, so plan time and fuel with a margin.

The Main Divide Traverse

~50mi↓ GPX

The signature Santa Ana day: climb to the crest and ride the spine the length of the range.

Climb Indian Truck Trail (5S01) from the Corona side up to the crest, then run the full North Main Divide (3S04) over the shoulder of Saddleback and continue onto the South Main Divide (6S07) toward the Ortega Highway. A big, exposed, all-day plated ride along the top of the range, high-clearance dual-sport and adventure terrain, no green-sticker bikes. Carry water and watch the sky: the Divide bakes in the heat and the clay turns greasy after rain, when the gates often close. One current caveat: the range sits in the Trabuco district's Airport Fire burn area, and as of 2026 parts of this traverse are closed or gated, including Indian Truck Trail and stretches of the North Main Divide. Check the forest's current alerts before counting on the full run.
