From Ensenada go South on hyway one to km marker 78 - half km past, make a right on the side road to Erindera. Go to km marker 9 - you'll see the guard house and the entrance to Baja 14 on your right. You can see much of the operation from the road.
The road is off of Hyway One - North of San Vicente. The road leads to Erindera - a nice little town on the coast. I'm sure you can see it with Google Earth.
