Nestled in the Sierra Nevada foothills approximately thirty miles northeast of Sacramento, Mammoth Bar delivers an immediate challenge to riders with its network of steep, narrow pathways that demand technical skill from the first turn. The 1,200-acre facility features over 30 miles of clearly marked and rated singletrack, where most routes plunge directly into demanding terrain without warm-up sections. Riders encounter a mix of rocky, technical sections on expert and moderate trails, though shaded areas along most pathways provide respite from the elements. The system includes both directional and bidirectional routes, complemented by a dedicated motocross circuit and specialized trials zones for varied riding experiences.
Beyond the challenging terrain, Mammoth Bar operates under weather-dependent scheduling with trail access limited to Tuesday, Wednesday, Friday, and Saturday, while the main MX track runs only Friday and Saturday during peak season. The area closes during wet conditions following specific precipitation thresholds to protect the trails, and Sunday typically sees the heaviest rider traffic. Located within the Auburn State Recreation Area alongside the Middle Fork of the American River, the venue offers scenic mountain vistas but minimal amenities - parking can be limited with few shaded spots, and facilities include only basic restrooms and picnic tables without potable water. Registration requirements include valid OHV permits, spark arresters, and adherence to noise regulations for this long-established riding destination.Dirt Bike Trail System
