Please submit any useful information about climbing South Mountain (New Mexico) that may be useful to other climbers. Consider things such as access and accommodation at the base of South Mountain (New Mexico), as well as the logistics of climbing to the summit.
Yes there is BLM land 6 miles north of the mountain. South Mountain is completely surrounded by private land and there is no public access to South Mountain without private land owner permission.
Tough hike, no trails. Hard to find access without going through private land. There is a BLM area on the north side on 344 you can use as a starting point. Park close to the road as the area is a popular shooting range which can have obvious dangers if someone doesn't know you are down range. Much prettier and less dangerous hikes out there, I would recommend avoiding this one.
