Railroad Tunnel No. 27 of the Sierra Greenway Nature Trail. Located 385 meters from the previous tunnel, it is 68 meters long and not equipped with artificial light, so it is advisable to have a flashlight.
This tunnel is dug in clays of different colors known as Triassic iridescent clays, or as variegated clays, because of the random combination of colors they present in the field.
