The Lost Mine Trailhead is on Basin Junction Road near the Chisos Basin Campground. The parking area is small (about 15 cars), so it’s a good idea to get there early. In case you’re wondering, 9:30am is not early. There were no spots, but we found another tiny lot about a quarter-mile east and road-hiked back to the trailhead. The mileage on this hike includes that extra distance, but the coordinates represent the actual trailhead.
Your mileage may vary.
As on our South Rim Loop hike (read here), we were starting in the shadow of Casa Grande Peak; this time to the east of that majestic alp. We started off uphill directly into the blinding morning sun. The temperature was hovering around 50°F, and the sky was a brilliant azure broken only occasionally by a fluffy white cloud. The first hundred yards or so was paved, but the trail soon turned to gravely dirt and began to narrow. We were hiking into the same autumn-colored forest that we had enjoyed a few days before. Casa Grande again peeked over a mottled sea of red, orange, and brown.
After gaining some altitude, we we were able to look west through The Window and see the rumpled Texas desert stretching off to the horizon. The higher we climbed, the better the view. Soon we were getting views to the south as well, down into Boot Canyon. Twisting and turning, we wound our way east toward Lost Mine Peak. The countryside was stunning; much more open than the South Rim Loop (the rim itself being a noteworthy exception, with some of the most expansive views we’ve ever seen). Still, this climb was a delight; at every turn in the trail we had a different vista to view.
