Corral Hollow Pass originally Portezuela de Buenos Ayres (Pass of Good Winds) is a mountain pass in the Diablo Range southeast of Livermore in Alameda County California. This pass at an elevation of 1600 ft was the point where El Camino Viejo crested the range leaving the Arroyo Seco watershed in the southeastern part of the Livermore Valley and dropping down a deep canyon into Corral Hollow near the former mining town of Tesla.
