Gilman Tunnels take you through the Jemez Mountains of NM

# The Gilman Tunnels: A Hidden Gem in New Mexico's Jemez Mountains

Ready for a road trip that feels straight out of a movie? That's because it literally has been! Tucked into the stunning Jemez Mountains of northern New Mexico, State Highway 485 winds through the historic Gilman Tunnels—a pair of massive stone tunnels blasted out of solid rock back in the 1920s. You'll find them near the charming town of Jemez Springs in Sandoval County, nestled within the Santa Fe National Forest.

Here's the deal: the road is fully paved but narrow and twisty with plenty of blind curves that'll keep you on your toes. It's a smooth drive with moderate grades and usually quiet (though expect more company on summer weekends). Once you pass through the tunnels, the road transforms into gravel Forest Service Road 376—not ideal for regular sedans, so fair warning there.

**Timing matters**: This area gets serious snow, so expect closures from mid-December through mid-April. Falling rocks can shut things down anytime, and there's zero cell service out here, so come prepared.

The tunnels have serious history. They were originally carved out for the Santa Fe Northwestern Railway's logging operations in the early 1900s. After the 1929 stock market crash and subsequent flood damage in 1941, the railroad shut down for good. Eventually, those tunnels became the incredible scenic road you see today, named after railroad CEO William H. Gilman.

And here's the Hollywood connection: those tunnels aren't just photogenic—they're movie-star photogenic. They've been featured in *3:10 to Yuma*, *The Lone Ranger*, and *The Scorch Trials*.

Don't skip the full experience. After the second tunnel, you'll discover a gorgeous waterfall and plenty of rocks perfect for stretching your legs. The stunning views of the box canyon and the Guadalupe River 500 feet below are absolutely worth the drive. Just bring your camera—you'll want it.
