Wills Canyon is part of the Benson Ridge complex in the Lincoln National Froest. There are a number of trails in the area and most follow the old rail beds for the most part. I'll check the maps but this looks like an 8 mile loop returning to the Bluff Springs Recreation area. It's a nice area that I was introduced to by a fellow hiker. It's about a 2 hour drive and a 4 hour hike so we should be back to Las Cruces by 5:30, unless we want to hang out after the hike and break out the grill????
Let me know if you'd be interested in having some eats after the hike.
