Big Bear’s trail system is one of Southern California’s most expansive and diverse high-altitude networks — a connected landscape of singletrack, fire roads, alpine routes, and endurance corridors designed for performance.
This isn’t one trail.
It’s a system.
At 6,000–8,000+ feet, the trails deliver the perfect combination of altitude, distance, and terrain variability — making them ideal for athletes across disciplines.
From recovery miles to peak conditioning blocks, the trails adapt to the athlete — not the other way around.
The trail network offers hundreds of miles of connected routes, allowing athletes to train for distance, elevation, and time on feet — all at altitude.
Every mile compounds. Every session builds.
