CONS

Overview
Lost Horse Mine blends Wild West history with classic desert scenery. You’re hiking to one of the area’s most productive historic mines, where the fenced mill ruins sit on a windswept ridge with wide-open views. Expect a rewarding walk that’s more about atmosphere and story than intact structures—the headframe is gone and remaining features are protected behind fencing.
What you’ll see
- The mine’s preserved mill remains, viewed from just outside the fence at the trail’s high point.
- Big panoramas across Lost Horse Valley and rolling, rocky hills.
- Groves of resilient Joshua trees and desert scrub, plus scattered relics and stone foundations; the longer loop passes additional ruins and old shafts (keep your distance).
Hike options & logistics
- Out-and-back: about 4 miles round-trip with roughly 550 feet of gain to the main ruins—moderate and steady.
- Full loop: about 6.2–6.5 miles with around 1,300 feet of cumulative gain, adding more ruins and broader views with a quieter feel beyond the mine.
- Access: The trailhead is off Keys View Road, with a short, well-graded dirt approach that’s passable for most passenger cars. There’s a small parking area and vault toilets at the trailhead; there’s no water.
Best time to visit
Aim for cool days in fall, winter, or spring. Start early to beat heat and wind, and for softer light on the ruins and surrounding hills. Weekdays and the loop section tend to feel quieter.
Wildlife
This is classic Mojave habitat—keep an eye out for lizards, jackrabbits, and birds of prey; coyotes are occasional. Sightings vary with temperature and time of day.
Safety & etiquette
The route is almost entirely exposed. Carry ample water, sun protection, and sturdy footwear for occasional loose gravel. Respect fencing and posted closures; old shafts and structures are hazardous. The site is actively protected—treat it gently and report vandalism if you encounter it.
