Trail Overview
Mortero Wash
This route takes you through some cool, historic structures including a railroad station and water tower. It also grants access to great hiking to Indian Hill Archeological Site and Carrizo Gorge. There is camping available, but make sure you watch for restrictions. Street-legal vehicles only.
It took 12 years to build the 11 miles of railroad through hellish Carrizo Gorge. Twenty-one tunnels and 14 trestles were needed including curved Goat Canyon Trestle. It’s a difficult hike to this trestle but worth the effort. The railroad operated over 50 years starting in 1919. Learn more at the Anza-Borrego State Park Visitor Center.
Getting There
