Gilman Tunnels

Gilman Tunnels take you through the Jemez Mountains

Nestled in New Mexico’s Jemez Mountains, in Sandoval County, in USA, the Gilman Tunnels blasted out of the rock in the 1920’s, were originally used for a logging railroad and are quite high. The tunnels have been the filming locations of several Holywood hits.

Located near the town of Jemez Springs, the road through the tunnels bears the designation Forest Service Road 376. It’s paved but very narrow. This road has an excellent surface, grades are moderate, and traffic is very light (heavier on summer weekends). They were named after William H. Gilman (one-time CEO of the SFNW Rail Road). Just past the tunnels, the pavement ends. In fact, there is a gate across the road at that point which is often closed well into May because of snow and poor road conditions until the spring and summer heat dries things out.

The road, with some narrow parts, sits on the Jemez Ranger District of the Santa Fe National Forest. Not recommended if you don't know how to reverse. Rock slides can occur anytime. The route was part of the former Santa Fe Northwestern Railway (SFNW). It was used in the early 1900s to haul lumber from the Jemez. The railroad never fully recovered from the Great Wall Street Crash of 1929 and ceased operations in 1941 following flood damage from the river. The Guadalupe River surges below the tunnels, through the Guadalupe Box Canyon. After the second tunnel you will find a beautiful waterfall and many rocks to climb around and rest on.

This is a remarkable road trip. Remember to bring your camera. Make sure you leave enough time to make plenty of stops along the way. It’s a two old large stone logging rail tunnels perched high about the Guadalupe River, offering stunning views of the box canyon and Jemez. This beautiful loop drive from the Elk Mountain Lodge is a must do. This roadside attraction offers stunning views, both of the tunnels themselves, and also of the beautiful box canyon and the Guadalupe River, below. The Gilman Tunnels were used in the filming of the 2007 motion picture 3:10 to Yuma.
