The hike to Lost Horse Mine is gentle with just a slight uphill grade. There are Joshua trees and yucca along the trail, and the surrounding landscape really comes alive during wildflower season. Outside of that time, the surrounding boulder strewn ridges can actually become monotonous en route to Lost Horse Mine.

From the trailhead, Lost Horse Mine Trail heads east, before turning southeast toward Lost Horse Mine. After a few miles, the trail will begin to cling to the north side of a rocky slope. Wrap around a pair of ravines to spot Lost Horse Mine. The tall, intact mill is enclosed by a chain-link fence, so you must admire it from a safe distance.

If you hike to Lost Horse Mine, it is advised to go the extra mile, or in this case the extra third of a mile, and continue up the steep ridge behind the mine to a vast overlook. You can return the way you came or follow a loop back to the trailhead. The loop is described in detail in Hiking California’s Desert Parks by Bill and Polly Cunningham. No permit is required to hike to Lost Horse Mine, so get out and enjoy!
