Seasonal Sonora Pass corridor: Use the signed Disaster Creek Trailhead access in Carson-Iceberg Wilderness, Stanislaus National Forest, California. Highway 108 and its forest-road approaches are seasonal and can close for snow or fire. Verify the selected road, parking area, and permit-issuance instructions. Highway 108 and its trailhead spurs are typically closed by winter snow, with reopening controlled by conditions. Wilderness permit dates are an authorization rule, not a closure season.
Check Caltrans, Stanislaus alerts, and the selected forest road before travel; do not use the permit season as proof that the road is open.
