The upward climb out of Salas meets the road at El Llanón, which is easy to miss as its infrastructure counts for little more than an abandoned rest stop along the road.
Not long ago this junction posed problems, but the way is now clear. Turn right here and follow the road. You will cross under a pair of large elevated roadways, take a wide turn in the road, and then pass back under the same roadways. Shortly afterwards the camino abandons the road and turns up to the left.
