Several have mentioned taking the 1st entrance to access Dog Canyon Dispersed Camping, but have not mentioned what road you turn off and how far from the main highway out of Alamagordo. That information would be helpful - Thanks!
A google earth measurement is 2.95 mi from Hwy 54 but the easy way to tell is that just before that 3 mile distance there is a large man made pile of earth on the right just before a cattle guard. Right after crossing the cattle guard the road curves to the left. The turn off to the right into the dispersed camping area is right in the middle of the Dog Canyon Road curve to the left. 32 44 41N 105 56 02W
Head south on the 54 from Alamogordo, then turn east on A16. From what I can see on Google maps, it's about 4 miles in on a good dirt road. Turn right after you go over the cattle guard.
If you put Dog Canyon Road into Google maps, it should take you there.
After turning onto Dog Canyon road off of highway 54, drive 3.1 miles and turn right on the dirt road leading into the campground. There is a faded red BLM sign that says the area is closed to target shooting.
I’ll update my review with this info for others. Thanks!
There are a few areas of dispersed camping. For the area i was in I turned right off of W Tucson-Ajo Hwy onto S San Joaquin Rd. There will be a dirt road right when you turn and that is the entrance. You will see campers everywhere. Impossible to miss!
