About 10 miles of the old, abandoned Alamogordo and Sacramento Mountain Railroad grade that runs from Alamogordo to Cloudcroft have been converted to rail trails in various sections, and are open to the public. The sections are separately accessible and have different degrees of difficulty, from easy walking at a grade of less than 6% to an eight mile loop that consists of an elevation change of about 1,000 feet and a few steep slopes. The altitude change is from 8650 feet at the Trestle Recreation Area to 7680 feet at the bridge.
Once entering the trail turn right almost immediately onto the Village Spur trail (5001A), which leads to 5001; at this point, it is on an old railroad bed. Turn right on the railroad bed. Soon you will see spectacular views of White Sands National Monument, the Tularosa Basin, and the San Andres Mountains. After you make the turn through the Devil's Elbow, you will see on your left the remains of the Trestle. Continue on 5001, which will soon leave the railroad bed and plunge into a canyon thick with old growth forest. At the bottom of the canyon go left on 5001C. (If you want to visit the Mexican Canyon Trestle, don't take the left turn yet; continue on 5001 up the other side of the canyon, back on the railroad bed and out to the overlook, and return by the same route.)
5001C goes down the canyon until it meets 5002, the Old Road. Continue down the canyon on 5002 until you come to the bridge over 82. (You will pass an intersection with 5004; this is where you will return to 5002. After you cross the bridge you will be on the Switchback Trail, 5004.
When you come to the railroad grade, turn right. (Turning left will take you a little way down the grade to a shelter containing pictures and descriptions of the switchback.) The grade, and the trails that lead through the canyons that once held trestles, will bring you to Bailey Canyon Road, which is a gravel forest road. Turn right, and almost at once turn left on the signed 5004 trail that takes you down a canyon and under Highway 82. Follow the trail until you come back to 5002 (the Old Road). Ride up the canyon. When you come to 5001C, don't take it - instead, bear right and stay on the Old Road until it intersects the railroad bed (5001) just a few feet past the Village Spur Trail (5001A).
Look to your left; you will see the signs. Take the Village Spur Trail back to the parking lot where you started.
The Trestle Recreation Area has restrooms, picnic tables, an overlook and interpretive signs.
