Guadalupe Ridge Trail (GRT)

The Guadalupe Ridge Trail is not a day hike — it is a hundred-mile odyssey that stitches together two national parks, a national forest, and BLM land into one of the most ambitious through-hikes in the American Southwest. You will cross the full spine of the Guadalupe Mountains, traversing high desert ridgelines where the wind never stops and the views stretch into forever. The terrain is relentlessly rocky — ancient Permian reef limestone that will chew through cheap boots in two days. Water sources are essentially nonexistent, so every ounce you carry is life. The landscape shifts from the Chihuahuan Desert floor through pinyon-juniper woodland to ponderosa pine at the higher elevations, with the occasional shock of McKittrick Canyon's fall color. This is a trail for seasoned backpackers who want genuine wilderness solitude — you might go days without seeing another person.
