In southern Anza Borrego Desert rests the largest freestanding wooden trestle in the entire world: the Goat Canyon Trestle. Built in 1932, this engineering marvel requires a 16+ mile round trip hike across (as of this writing) abandoned railroad tracks, through train tunnels, and over smaller wooden railroad trestles. By the time you see the trestle, it's clear why this railroad was deemed "the impossible railroad."
