Rubithon is an annual gathering of Toyota 4X4s in Rubicon Trail, Northern California, one of the most challenging and threatened trails in the US. The trail with a distance of 11.5 miles of mostly diamond-rated (difficult) off-road trail will test your nerve, your driving skills and your rig. The more skilled you are, and the more trail-ready your rig is, the better chances for you in surviving the trail unscathed. It is an adventure of the lifetime, meeting fellow Toyota off-road enthusiasts and enjoying the scenic view of the El Dorado national forest.
