This is a drive-up from the Mil Potrero Highway of about 3 miles on dirt road. I recommend high clearance (more than a sedan) but it didn't require more than 2WD and I made it fine in my outback. The turnoff is within .5 miles of the turnoff to W6/SC-001, Cerro Noroeste, which would be a good one to double with this one.

The AZ is pretty large and includes the road, but if you want to got to the actual summit, it's a light bushwhack from the road. If you follow the road to the end, there is a great view off the edge. Big area to park, and you could turn around with your overland trailer.
