South Halfmoon Gulch/Iron Mike Mine

South Halfmoon Gulch is a classic Colorado 4WD trail that combines thick conifer forest, creek crossings, rocky climbs, and wide open alpine terrain. The trail starts narrow and shaded, winding through dense pine forest on a rough dirt road with embedded rock, ruts, and exposed roots. A notable feature early on is a creek crossing with a steep rocky climb out. Water depth varies depending on runoff and snowmelt, but late summer and fall usually offer a shallow, rocky crossing. Slick stones and large boulders can make this section technical in any conditions. A nearby winch-anchor sign serves as a reminder that recovery gear may be necessary. Beyond the creek, the trail climbs steadily and becomes rockier, with loose sections and mild off-camber spots. Low range helps with control rather than necessity. As elevation increases, trees thin and the landscape opens into an alpine basin dotted with historic mining remnants from the Iron Mike Mine era. The trail ends in wide-open terrain with incredible views of Mount Elbert and Mount Massive—an ideal place to stop, explore, and take in the quiet. South Halfmoon Gulch isn’t extreme, but it offers a rewarding mix of scenery, history, and classic 4WD driving.
