In reply to Emilysaladfingers:
I used gold car when I was there twice last year. They were absolute shite and I would never use them again, so don't use them.
Ref driving to makinodromo, I have done it but it isn't simple. Go out of the gorge towards desplomilandia. After the damstake the right hand fork after the little roundabout. Drive up there for miles. There is a dirt track on your right that goes up towards a col, there was a chain across this, when I was there but you could move it. This track then takes you up to a col, park there and head down And right to the crag.
Be warned not simple and this beta is from years ago when I was there.
Good luck.
Ps better to walk in with bivy gear plus food etc.
